The Castle Fire killed likely more than a thousand giant sequoias — including many that had stood for well over 500 years and some for 1,000 — on the western slopes of California's Sierra Nevada mountains, the Los Angeles Times reported.

Languishing in the soft, silty mud, the living fossil looked as if it didn't have a care in the world as it feasted on the fish left stranded in the tidal mangrove pools of the Sungei Buloh wetlands. However, the saltwater crocodile (Crocodylus porosus) might have been a little less at ease if it knew nearly 90% of its mangrove habitat in Singapore has been lost over the past century.

She said that problems with reforestation projects often arise when the wrong species are planted at the wrong sites. But she adds there are key signs when reforestation has been done effectively.</p><p>"High survival and growth rates and healthy forests of the correct trees species," Primavera told Mongabay. "For mangroves, for example, these would be <em>Avicennia marina </em>and<em> Sonneratia alba </em>along coastlines facing the open sea<em>. </em>For terrestrial species these would be native species and not exotics."</p><p>To safeguard the trees, NParks carries out regular inspections and offers best-practice workshops to organizations across the island.

Like many other plant-based foods and products, CBD oil is one dietary supplement where "organic" labels are very important to consumers. However, there are little to no regulations within the hemp industry when it comes to deeming a product as organic, which makes it increasingly difficult for shoppers to find the best CBD oil products available on the market.

With massive fronds creating a luxuriously green canopy in the understory of Australian forests, tree ferns are a familiar sight on many long drives or bushwalks. But how much do you really know about them?
Ferns are often the first plants to grow back after bushfires. Greg Moore, Author provided
Ancient Family Ties<p>Tree ferns are generally slow growing, at rates of just 25-50 millimeters height increase per year. This means the tall individuals you might spot in a mature forest may be <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5426625/#:%7E:text=The%20tree%20fern%20species%20in,grow%20to%2020m%20%5B16%5D." target="_blank">several centuries old</a>.</p><p>However, in the right environment they can grow faster, so guessing their real age can be tricky, especially if they're growing outside their usual forest environment.</p><p>As a plant group, tree ferns are ancient, dating back <a href="https://www.nzgeo.com/stories/ferns-the-glory-of-the-forest/" target="_blank">hundreds of millions of years</a> and pre-dating dinosaurs.</p><p>They existed on earth long before the flowering or cone-bearing plants evolved, and were a significant element of the earth's flora during the <a href="https://www.nationalgeographic.com/science/prehistoric-world/carboniferous/" target="_blank">Carboniferous</a> period 300-360 million years ago, when conditions for plant growth were near ideal. This explains why ferns don't reproduce by flowers, fruits or cones, but by more primitive spores.</p><p>In fact, fossilized tree ferns and their relatives called the fern allies laid down during the carboniferous then have provided much of the earth's fossil fuels dating from that period. And tree ferns were a great <a href="https://trove.nla.gov.au/work/9452631" target="_blank">food source</a>, with Indigenous people once <a href="https://museumsvictoria.com.au/bunjilaka/about-us/the-plants-of-milarri-garden/" target="_blank">eating the pulp</a> that occurs in the center of the tree fern stem either raw or roasted as a starch.</p><p>Until recent times, ferns were quiet achievers among plant groups with an expanding number of species and greater numbers. Today, human activities are limiting <a href="https://www.environment.gov.au/system/files/resources/28b03b9a-2b02-4a50-82d0-54697736ab6e/files/threatened-tasmanian-ferns.pdf" target="_blank">their success</a> by the clearing of forests and agricultural practices. Climate change is also a more recent threat to many fern species.</p>
Species You’ve Probably Seen<p>Two of the more common tree fern species of south eastern Australia are <em><a href="https://www.anbg.gov.au/gnp/interns-2003/cyathea-spp.html" target="_blank">Cyathea australis</a></em> and <a href="https://www.anbg.gov.au/gnp/interns-2003/dicksonia-antarctica.html" target="_blank"><em>Dicksonia antarctica</em></a>. Both species have a wide distribution, extending from Queensland down the Australian coast and into Tasmania.</p><p>They're often found growing near each other along rivers and creeks. They look superficially alike and many people would be unaware that they are entirely different species at first glance. That is, until you look closely at the detail of their fronds and run your fingers down the stalks.</p><p><em>C. australis</em> has a rough almost prickly frond, hence its common name of rough tree fern, and can grow to be 25 meters tall. While <em>D. antarctica</em>, as the soft tree fern, has a smooth and sometimes furry frond and rarely grows above 15 meters.</p><p>Both contribute to the lush green appearance of the understory of wet forests dominated by eucalypts, such as mountain ash (<em>Eucalyptus regnans</em>).</p>
Stems That Host a Tiny Ecosystem<p>The way tree ferns grow is quite complex. That's because growth, even of the roots, originates from part of the apex of the stem. If this crown is damaged, then the fern can die.</p><p>At the right time of the year, the new fronds unfurl in the crown from a coil called a fiddlehead. The stem of the tree fern is made up of all of the retained leaf bases of the fronds from previous years.</p><p>The stems are very fibrous and quite strong, which means they tend to retain moisture. And this is one of the reasons why the stems of tree ferns don't easily burn in bushfires — even when they're dry or dead.</p><p>In some dense wet forest communities, the stems of tree ferns are a miniature ecosystem, with epiphytic plants — such as mosses, translucent filmy ferns, perhaps lichens and the seedlings of other plant species — growing on them.</p><p>These epiphytes are not bad for the tree ferns, they're just looking for a place to live, and the fibrous, nutrient-rich, moist tree fern stems prove brilliantly suitable.</p>
Engulfed by Trees<p>Similarly, the spreading canopies of tree ferns, such as <em>D. antarctica</em>, provide an excellent place for trees and other species to germinate.</p><p>That's because many plants need good light for their seedlings to establish and this may not be available on the forest floor. Seeds, such as those of the native (or myrtle) beech, <em>Nothofagus cunninghamii</em>, may germinate in the crowns of tree ferns, and its roots can grow down the tree fern trunks and into the soil.</p><p>As time passes, the tree species may completely grow over the tree fern, engulfing the tree fern stem into its trunk. Decades, or even centuries later, it's sometimes still possible to see the old tree fern stem embedded inside.</p><p><span></span>Still, tree ferns are wonderfully resilient and give a sense of permanence to our ever-changing fire-affected landscapes.</p>

Warming temperatures on land and in the water are already forcing many species to seek out more hospitable environments. Atlantic mackerel are swimming farther north; mountain-dwelling pikas are moving upslope; some migratory birds are altering the timing of their flights.
Numerous studies have tracked these shifting ranges, looked at the importance of wildlife corridors to protect these migrations, and identified climate refugia where some species may find a safer climatic haven.
"There's a huge amount of scientific literature about where species will have to move as the climate warms," says U.C. Berkeley biogeographer Matthew Kling. "But there hasn't been much work in terms of actually thinking about how they're going to get there — at least not when it comes to wind-dispersed plants."
Kling and David Ackerly, professor and dean of the College of Natural Resources at U.C. Berkeley, have taken a stab at filling this knowledge gap. Their recent study, published in Nature Climate Change, looks at the vulnerability of wind-dispersed species to climate change.
It's an important field of research, because while a fish can more easily swim toward colder waters, a tree may find its wind-blown seeds landing in places and conditions where they're not adapted to grow.
Kling is careful to point out that the researchers weren't asking how climate change was going to change wind; other research suggests there likely won't be big shifts in global wind patterns.
Instead the study involved exploring those wind patterns — including direction, speed and variability — across the globe. The wind data was then integrated with data on climate variation to build models trying to predict vulnerability patterns showing where wind may either help or hinder biodiversity from responding to climate change.
One of the study's findings was that wind-dispersed or wind-pollinated trees in the tropics and on the windward sides of mountain ranges are more likely to be vulnerable, since the wind isn't likely to move those dispersers in the right direction for a climate-friendly environment.
The researchers also looked specifically at lodgepole pines, a species that's both wind-dispersed and wind-pollinated.
They found that populations of lodgepole pines that already grow along the warmer and drier edges of the species' current range could very well be under threat due to rising temperatures and related climate alterations.
"As temperature increases, we need to think about how the genes that are evolved to tolerate drought and heat are going to get to the portions of the species' range that are going to be getting drier and hotter," says Kling. "So that's what we were able to take a stab at predicting and estimating with these wind models — which populations are mostly likely to receive those beneficial genes in the future."
That's important, he says, because wind-dispersed species like pines, willows and poplars are often keystone species whole ecosystems depend upon — especially in temperate and boreal forests.
And there are even more plants that rely on pollen dispersal by wind.
"That's going to be important for moving genes from the warmer parts of a species' range to the cooler parts of the species' range," he says. "This is not just about species' ranges shifting, but also genetic changes within species."
Kling says this line of research is just beginning, and much more needs to be done to test these models in the field. But there could be important conservation-related benefits to that work.
"All these species and genes need to migrate long distances and we can be thinking more about habitat connectivity and the vulnerability of these systems," he says.
The more we learn, the more we may be able to do to help species adapt.
"The idea is that there will be some landscapes where the wind is likely to help these systems naturally adapt to climate change without much intervention, and other places where land managers might really need to intervene," he says. "That could involve using assisted migration or assisted gene flow to actually get in there, moving seeds or planting trees to help them keep up with rapid climate change."

Not too long ago, many people weren't sure if trees had a place in cities. People, cars, houses and buildings made up urban areas — there wasn't much room for nature.
As Cities Evolve, Trees Keep Us Grounded.<p>Trees are powerhouses when it comes to regulating city microclimates — filtering air pollution, providing shade, absorbing CO2, helping prevent flash flooding, as well as acting as an important antidote to the urban heat island effect that makes cities far hotter than surrounding rural areas.</p><p>"Trees can make a huge difference to a city's temperature," says Tobi Morakinyo, an urban climatologist whose <a href="https://www.sciencedirect.com/science/article/abs/pii/S2212095513000084" target="_blank">research</a> into the cooling effect of trees in Akure, southwest Nigeria, showed using trees to shade buildings could cool them down by up to five degrees Celsius.</p><p>In hot sub Saharan African cities like Akure — where average maximum summer temperatures can reach 38 degrees (100 degrees F) — Morakinyo says trees' cooling effect is an important tool councils can wield against both heat stress and cooling costs.</p><p>Alongside the eco-services urban trees provide, there are also the qualities "that we can't put monetary value on," adds Cris Brack, a forest ecologist from the Australian National University and director of the National Arboretum in Canberra. </p><p>Those are "biodiversity, aesthetics and our visceral, gut-need to experience nature," Brack told DW, referring to the concept of 'biophilia' — the idea that humans have an innate desire to connect with nature. Mounting <a href="https://www.nature.com/articles/srep11610" target="_blank">evidence</a> shows that people who live in places with more trees experience lower levels of stress and <a href="https://www.nature.com/articles/s41593-019-0451-y" target="_blank">mental illness</a>, even when controlling for socio-economic factors.</p>
Trees Make Us Feel Good — Do We Return the Favor?<p>Though our need for trees in cities appears to only be becoming greater, they often battle oppressive urban environments. Street trees are "in a constant struggle" for space in cities, says Brack, where below ground their root systems can be choked by water pipes, roads and underground car parks, and above ground by pollution, power lines and traffic.</p><p>They also face mechanical damage from cars, battering from increasingly extreme weather conditions and regular uprootings to make way for construction sites.</p><p>Perhaps the most damaging modern challenge for city trees, though, says Somidh Saha, urban forest ecologist at the Karlsruhe Institute of Technology in Germany, is drought. Following Europe's unprecedented heatwave in 2018, a study co-authored by Saha found 30% of the trees planted in Karlsruhe in southwestern Germany over the previous four years had died — both directly and indirectly because of a lack of water.</p><p>"Without enough water, trees become weak and that makes them vulnerable to disease," Saha told DW. At the same time, declining city populations of birds and arboreal mammals, such as bats, leaves insect populations unchecked, and local trees susceptible to their growing numbers.</p>
Seeing the Forest for the Trees<p>Ambitious greening projects have cropped up in several megacities around the globe in recent years. New York City planted a million trees between 2007 and 2015, London mayor Sadiq Khan hopes to green more than half the capital by 2050 to make the world's first "National Park City," while Paris announced it would build four inner-city urban forests throughout 2020.</p><p>But outside the Global North, in places such as Saha's native India and Morakinyo's native Nigeria, where they cite a lack of resources and political will as big barriers to making urban greenery a priority, trees in cities are much scarcer.</p><p>As climate change brings hotter temperatures and unpredictable downpours, cities are demanding a new kind of resilience from urban trees. For many cities in the world, ecologists say that means planting more exotic species of trees.</p><p>While many people are opposed to the idea of planting non-native species, ecologists Brack and Saha say alternative species are usually better adapted to the artificial environment of a city — especially in the face of increasing heatwaves.</p><p>The three-toothed Maple, native to China, Korea and Japan, is one species that could appear in greater numbers in other parts of the world as temperatures rise. </p><p>There's also an important distinction to be made between "exotic" trees, which just means they aren't local, and "invasive" trees, which are harmful — spreading very quickly and dominating the environment. As for local wildlife, while ongoing studies are being carried out in places like Germany by Saha's team, Brack says in his local Canberra, where almost all tree species in the city are exotic, birds happily eat fruit from non-natives and mammals alike find homes wherever there is an appropriate hollow.</p>
Citizens Pitch In<p>One solution to preserving city trees that's grown in popularity in recent years is citizen involvement in urban tree caretaking. New York City's citizen pruner program allows city dwellers to take classes to become official city tree carers, and Berlin — a place that has typically excluded citizens from looking after urban flora — is now allowing residents to apply for permits to maintain tree pits and has proposed that they water city trees in summer.</p><p>Involving citizens has its pros and cons, Dümpelmann says, and these kinds of programs may or may not be effective depending on the culture of the city – but even watering trees alone "has been shown to be a really relevant maintenance effort."</p><p>While planting trees in urban spaces is an effective and fairly efficient way to adapt to climate change, Dümpelmann stresses that it isn't a holistic solution.</p><p>"It's something we should work on while at the same time addressing the root causes of climate change," she said. </p><p>Beyond using trees as geo-engineering fix, urban ecologists point out that more trees in cities could change perspectives on urban living and give people a greater understanding of how to value nature as part of a sustainable, livable city – not separate from it.</p><p>That means seeing trees as living, growing beings, Brack says – not fixed in time, or immune to the stressors of living in harsh urban environments.</p>

For 20 years, the Colima fir tree (Abies colimensis) has been at the heart of many disputes to conserve the temperate forests of southern Jalisco, a state in central Mexico. Today, the future of this tree rests upon whether the area's avocado crops will advance further and whether neighboring communities will unite to protect it.
The Nevado de Colima volcano stands 4,260 meters (13,976 feet) above sea level. Agustín del Castillo<p>According to biologist José Villa Castillo, the director of Nevado de Colima National Park and Nevado de Colima Cloud Forest State Park, it is imperative to stop the commercialization of the tree's timber and to create policies that conserve the forests in which it lives. Villa Castillo also supported the inclusion of the tree on the endangered species list.</p><p>Villa Castillo acknowledged the enormous challenge of conserving this tree, and he said the pressure to exploit its timber without sustainable management is far from the only problem. The expansion of the nearby avocado industry also threatens its survival.</p><p>When allowed to grow, the Colima fir tree can become monumental: It can reach 60 meters (196 feet) in height and 2 m (6.5 ft) in diameter. To protect this giant, specialists and communities often promote ecotourism and conservation projects inside the national and state parks that surround the Nevado de Colima volcano.</p>
Fires That Clear Land for Avocado Crops<p>In 2012, a group of researchers from the University of Guadalajara proposed to the Secretariat of Environment and Natural Resources (SEMARNAT) the recognition of the <em>A. colimensis</em> as a unique species to differentiate it from the sacred fir (<em>A. religiosa</em>), which is the dominant fir tree in the Trans-Mexican Volcanic Belt, a collection of volcanoes in central Mexico.</p><p>The Colima fir tree "has extremely low genetic diversity; it has the lowest known genetic diversity among all the species in the Abies genus in Mesoamerica and one of the lowest among all the species of trees on the planet," according to the authors of the proposal to recognize the tree as an endangered species. The area it occupies "is very limited": just 15,002 hectares (37,071 acres), or 0.007% of the territory of Mexico.</p><p>The Nevado de Colima volcano, which stands 4,260 meters (13,976 feet) above sea level, is one of only eight peaks that exceed 4,000 m (13,123 ft) in Mexico. It is only 40 kilometers (25 miles) from the Pacific Ocean and is considered an "evolutionary island" because the ecosystems in its high-altitude areas drive unique adaptations in species and are cut off from other ecosystems by hundreds of kilometers. The Colima fir tree is an example of the area's biological differentiation, according to Libertad Arredondo, a researcher and expert on the ecology of high mountains.</p>
The fir forests are mainly located in the middle of slopes or in ravines. Agustín del Castillo<p>Even though the tree has remained on that "evolutionary island," its situation has become increasingly complicated by the impact of deforestation, which was propelled by the issuance of permits for forest exploitation. Fires, started to convert the land to agriculture or other uses, also present a threat to the ecosystem, according to the experts who suggested the tree should be considered endangered.</p><p>The researchers said the tree's future prospects are further complicated by its slow growth rate, its high degree of genetic erosion, the effects of climate change, and the movement of clouds to higher altitudes. The position of clouds is crucial because they act as an essential source of moisture for fir trees.</p><p>Villa Castillo, an expert in pine genetics and reproduction, said the Colima fir tree has never been successfully reproduced in nurseries, which would likely make it impossible to conduct reforestation efforts to help repopulate the species.</p><p>The forests that contain the Colima fir tree are in cold, humid climates, with very little light reaching the understory, and they're mainly located in the middle of slopes or in ravines. The species thrives when surrounded by oak trees, coniferous trees and other types of vegetation common in mountainous cloud forests. The tree also requires a primary habitat with little disturbance from humans.</p><p>According to Villa Castillo, fire kills most Colima fir tree seedlings, as it kills seedlings of other species in the <em>Abies</em> genus. In recent years, more fires have been started in the forest to clear the way for avocado trees.</p>
A tree and other vegetation in the cloud forest surrounding the Nevado de Colima volcano. Agustín del Castillo<p>Sonia Navarro Pérez, a researcher from the University of Guadalajara who has monitored and conducted biological inventories in the area, has seen firsthand how the growth of the avocado industry has led to the loss of important forested areas.</p><p>She described the case of the indigenous community of San José del Carmen, which is in the municipality of Zapotitlán de Vadillo, near one of the patches of forest.</p><p>"We were working with them to establish productive alternatives that are good for nature," Navarro Pérez said. "But when the avocado came, it overwhelmed us completely."</p><p>Since 2013, the coniferous forests around the Nevado de Colima volcano have lost nearly 6,600 hectares (16,300 acres) due to illegal logging, livestock rearing and intentionally set fires, according to Mexico's deforestation risk index developed by the <a href="https://www.gob.mx/inecc" target="_blank">National Institute of Ecology and Climate Change</a>.</p>
A section of cloud forest in San José del Carmen, inside the state park created in 2009. Community members have been protecting the forest voluntarily for over two decades. Agustín del Castillo<p>"[What was once] an original area of 7,000 hectares [17,300 acres] of fir-specific forest is now cut in half," said Villa Castillo, the director of the Nevado de Colima national and state parks.</p><p>The expansion of the avocado crops is the most recent threat in a series of events that have negatively impacted the conservation of the forests in the area.</p><p>Between the 1940s and the 1990s, the Atenquique Industrial Company had exclusive rights to use the timber from these forests under a concession from the Mexican government. The result was "that the forests were skimmed — that is, they took the best parts," Villa Castillo said.</p><p>When the concession expired in 1995, the forests did not experience a transition to a sustainable timber extraction method. Those who, along with landowners who held small plots, had rights to the shared land were limited to selling the forested areas, at very low prices, to the new logging industries located in Ciudad Guzmán. "Then, there were many abuses against the communities. The money was given to the caciques" — families who have always controlled the shared land — "alms were left for the community, and our forests were very poorly managed," said Rafael González Merín, the former president of Huescalapa, a collective of communally owned farmland known as an <em>ejido</em>.</p><p>As a result, many residents of the community believe the solution is to conserve the forests with productive projects.</p>
Communities Pitch in to Save Their Trees<p>Unlike the communities that have been overtaken by the avocado industry, Huescalapa has largely managed to resist its arrival. The community of shared land, which spans more than 1,200 hectares (3,000 acres), is home to pine and fir trees within its shady temperate forests.</p><p>The residents of Huescalapa have also set aside the proposals they've received from the forestry industry, which has expressed interest in buying their trees.</p><p>According to Gerardo Bernabé Aguayo, logging activity in this area of Jalisco "has been very negative because the industry has managed delicate areas — with very limited species — poorly, so we are supporting and launching projects with the communities." Bernabé Aguayo is the president of the board of trustees of Nevado de Colima and Adjacent Basins, a civil association created about 20 years ago after being promoted by the government of the state of Jalisco. To support the conservation of the national and state parks, the board has financing from the regional private sector.</p><p>The board manages about 6 million pesos ($268,000) contributed by the federal government in 2020. With resources from the private sector, it has been able to access an additional 1.5 million pesos ($67,000).</p>
An area of fir trees that has been destroyed by logging. Agustín del Castillo<p>Rodrigo Cantera Hernández, the president of the El Alcázar Ecotourism Center, said that in Huescalapa, the caciques removed timber from the fir forests, "but they did not report any money to the other community members, so we fought to eject them and were able to do so a couple of years ago."</p><p>In Huescalapa, three main conflicts over timber have taken place in the past 20 years. First, in 1999, a group of community members sold part of the forest to a forestry industry from Ciudad Guzmán. A movement led by citizens put an end to the logging five months later.</p><p>Next, in 2012, environmental authorities granted permission for forest exploitation in these areas, so fir trees continued to be cut down. An opinion by the <a href="https://www.ideaac.org.mx/" target="_blank">Institute of Environmental Law</a>, a civil society organization, cited scientific evidence that demonstrated the uniqueness of mountain fir trees and forced SEMARNAT to withdraw these permissions.</p>

The cooperative may receive an additional 3 million pesos ($133,800) in 2020 to purchase more equipment and improve the roads, but support for this funding was blocked in a community assembly. "They have not understood that it is for the benefit of everyone, that it is not money for our pockets," said Cantera Hernández, the president of the cooperative.</p><p>In Huescalapa, one of the challenges that interferes with efforts to promote the ecotourism center is the division that exists between community members.

She recalled that when loggers came with offers to buy the forest, members of the community believed that they offered very little payment and that "the damage [that the loggers left] was too much." For that reason, they decided "not to touch the forest, because it produces water for the crops and for our houses."</p><p>Cortés Reyes said the community was able to construct the ecotourism center because it had resources managed by the Nevado de Colima Cloud Forest State Park and by the Board of Trustees of Nevado de Colima and Adjacent Basins. However, she said it is important that more promotion is given to the area and that urgent problems, such as those with the water supply system, are resolved.</p>

"We are so certain of [the importance of] preventing logging that, long before the declaration of the natural protected area, our community assembly had already decided to save this forest. We will continue to be 'foolish' in this decision."</p>
On hot summer days, trees help cool city neighborhoods. And during extreme storms, they help absorb stormwater and reduce flooding.

Imagine an information superhighway that speeds up interactions between a large, diverse population of individuals, allowing individuals who may be widely separated to communicate and help each other out. When you walk in the woods, this is all happening beneath your feet. No, we're not talking about the internet, we're talking about fungi. As a result of a growing body of evidence, many biologists have started using the term "wood wide web" to describe the communications services that fungi provide to plants and other organisms.
All trees all over the world form a symbiotic association with below-ground fungi These are fungi that are beneficial to the plants and explore the soil. The fungi send mycelium, a mass of thin threads, through the soil. The mycelium picks up nutrients and water, brings them back to the plant, and exchanges the nutrients and water for a sugar or other substance made by photosynthesis from the plant.

This Win/Win Is a Mutually Beneficial Exchange.<p>While researching her doctoral thesis some 20+ years ago, ecologist Suzanne Simard discovered that trees communicate their needs and send each other nutrients via a network of latticed fungi buried in the soil – in other words, she found, they "talk" to each other.</p><p>Simard showed how trees use a network of soil fungi to communicate their needs and aid neighboring plants.</p><p>Since then she has <a href="https://e360.yale.edu/features/exploring_how_and_why_trees_talk_to_each_other" target="_blank">pioneered further research</a> into how trees converse, including how these fungal filigrees help trees send warning signals about environmental change, search for kin and how they transfer their nutrients to neighboring plants before they die.</p><p>All trees all over the world form a symbiotic association with below-ground fungi.
