How to Handle Raccoons, Snakes and Other Critters in Your Yard (Hint: Not With a Thermos)

By Leslie Burger
I heard a local story of a man who, in his excitement to kill a rattlesnake, used the only thing he had available ─ his thermos bottle. The next scene in this drama has the man in the hospital receiving anti-venom to treat a snake bite.
Encounters with wildlife are becoming more common in towns and neighborhoods as urbanization increases, and people often do not know what to do in these situations. Many species of urban wildlife, such as butterflies, bees, beetles, lizards, bats and most birds, are benign or even beneficial, helping to control mosquitoes, pollinate flowers and trees, recycle nutrients, and provide many other hidden ecological services.
But there can be also some associated health concerns, as some species bring the risk of parasites or disease. For example, some snakes like rattlesnakes or copperheads can be venomous. Habitat loss to fragmentation, urbanization and expanding agricultural production means suburban and urban spaces will increasingly become options for wildlife searching for new homes. It is not just snakes, but also coyotes, foxes, raccoons, deer and even bears.
As a wildlife biologist and extension educator, my job is to help people more fully understand wildlife for the betterment of both people and animals. People generally enjoy wildlife. Renowned ecologist E. O. Wilson coined the term "Biophilia" (meaning "life fondness") to describe this seemingly inherent affinity humans have for natural life. Rather than being too friendly or overly fearful, people should be aware and respectful of wildlife that may be in their neighborhood.
What About Those Snakes?
Many people ─ like the thermos-wielding man in the opening story ─ may not realize that snakes are beneficial and that attacking them with a dangerous tool, much less a thermos, is increasing the likelihood that it will be scared and bite in self-defense. About 7,000 to 8,000 people are bitten each year by a venomous snake, but death from one is very rare.
While they might not have the charisma of a panda or polar bear, snakes serve an important role in the environment. They eat insect pests as well as rodents that can serve as vectors for parasites and infectious diseases like the plague that may be transmitted to humans. True, a venomous snake hanging around the backyard would be a situation for concern. But since only 20 of the estimated 127 species in North America are venomous, the probability of encountering a venomous snake is pretty low. Nevertheless, if a venomous snake does end up near a home, wisdom calls for keeping children and pets away until professional help arrives to remove the animal.
Not-So-Adorable Raccoons
Most people aren't worried about a cute raccoon eating out of the cat's outdoor food dish. However, that same animal could be a carrier for rabies, parasites, influenza, salmonella or other pathogens that are issues for people and household pets. Close proximity to people and pets is discouraged for all wildlife species, even the cute ones.
What About Other Critters?
If wildlife such as coyotes, deer or foxes do appear in the yard, the best option for a peaceful encounter is to give them space. When met by people, most wild animals, if not habituated to humans, will either escape the imminent danger humans pose or hunker down to hide until the coast is clear for them to leave. It is when people move in closer ─ whether intentionally to help or harm or accidentally through unawareness ─ that a wild animal will feel the need to defend itself physically. For the untrained person, it is always wisest to go inside and wait it out.
Homeowners who don't want any furry or scaly visitors should be mindful not to provide food or shelter. Secure outdoor trashcan lids, scoop up spilled seed at bird feeders, and remove outdoor pet food bowls that may attract these creatures. Stacks of firewood and piles of yard debris provide shelter to smaller critters, so if this is not your goal, consider alternatives.
In those instances where an unwanted guest does not move on, it is best for all involved to contact local wildlife experts for assistance rather than trying to handle the situation without help from those with proper training. Not only will this avert any unwanted injuries to people or animals, it will also prevent any unintentional violations of the state and federal laws that protect most wildlife in the U.S.

What if You Want Some Backyard Wildlife?
Some folks want to create space for nature by offering the food, shelter and water that animals are seeking. This option helps restore some of the functions and services that natural ecosystems provide. Bird feeders, pollinator plantings, (unchlorinated) water features, and native trees and shrubs can be artfully incorporated into landscaping to provide beauty and supply backyard habitats. This is supplemental support and is different from caring for wild animals as if they were domesticated. Deliberately feeding animals like squirrels, deer or raccoons can create a hazardous situation for people and wildlife, leading to increased risk of negative encounters, disease and harm. This practice is not supported or encouraged by professional wildlife biologists.

The Science Behind Frozen Wind Turbines – and How to Keep Them Spinning Through the Winter
By Hui Hu
Winter is supposed to be the best season for wind power – the winds are stronger, and since air density increases as the temperature drops, more force is pushing on the blades. But winter also comes with a problem: freezing weather.

While traditional investment in the ocean technology sector has been tentative, growth in Israeli maritime innovations has been exponential in the last few years, and environmental concern has come to the forefront.

<p>The UN hopes that new investments in ocean science and technology will help turn the tide for the oceans. As such, this year kicked off the <a href="https://www.oceandecade.org/" target="_blank" rel="noopener noreferrer">United Nations Decade of Ocean Science for Sustainable Development (2021-2030)</a> to galvanize massive support for the blue economy.</p><p>According to the World Bank, the blue economy is the "sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem," <a href="https://www.sciencedirect.com/science/article/pii/S0160412019338255#b0245" target="_blank" rel="noopener noreferrer">Science Direct</a> reported. It represents this new sector for investments and innovations that work in tandem with the oceans rather than in exploitation of them.</p><p>As recently as Aug. 2020, <a href="https://www.reutersevents.com/sustainability/esg-investors-slow-make-waves-25tn-ocean-economy" target="_blank" rel="noopener noreferrer">Reuters</a> noted that ESG Investors, those looking to invest in opportunities that have a positive impact in environmental, social and governance (ESG) issues, have been interested in "blue finance" but slow to invest.</p><p>"It is a hugely under-invested economic opportunity that is crucial to the way we have to address living on one planet," Simon Dent, director of blue investments at Mirova Natural Capital, told Reuters.</p><p>Even with slow investment, the blue economy is still expected to expand at twice the rate of the mainstream economy by 2030, Reuters reported. It already contributes $2.5tn a year in economic output, the report noted.</p><p>Current, upward <a href="https://www.ecowatch.com/-innovation-blue-economy-2646147405.html" target="_self">shifts in blue economy investments are being driven by innovation</a>, a trend the UN hopes will continue globally for the benefit of all oceans and people.</p><p>In Israel, this push has successfully translated into investment in and innovation of global ports, shipping, logistics and offshore sectors. The "Startup Nation," as Israel is often called, has seen its maritime tech ecosystem grow "significantly" in recent years and expects that growth to "accelerate dramatically," <a href="https://itrade.gov.il/belgium-english/how-israel-is-becoming-a-port-of-call-for-maritime-innovation/" target="_blank" rel="noopener noreferrer">iTrade</a> reported.</p><p>Driving this wave of momentum has been rising Israeli venture capital hub <a href="https://www.thedockinnovation.com/" target="_blank" rel="noopener noreferrer">theDOCK</a>. Founded by Israeli Navy veterans in 2017, theDOCK works with early-stage companies in the maritime space to bring their solutions to market. The hub's pioneering efforts ignited Israel's maritime technology sector, and now, with their new fund, theDOCK is motivating these high-tech solutions to also address ESG criteria.</p><p>"While ESG has always been on theDOCK's agenda, this theme has become even more of a priority," Nir Gartzman, theDOCK's managing partner, told EcoWatch. "80 percent of the startups in our portfolio (for theDOCK's Navigator II fund) will have a primary or secondary contribution to environmental, social and governance (ESG) criteria."</p><p>In a company presentation, theDOCK called contribution to the ESG agenda a "hot discussion topic" for traditional players in the space and their boards, many of whom are looking to adopt new technologies with a positive impact on the planet. The focus is on reducing carbon emissions and protecting the environment, the presentation outlines. As such, theDOCK also explicitly screens candidate investments by ESG criteria as well.</p><p>Within the maritime space, environmental innovations could include measures like increased fuel and energy efficiency, better monitoring of potential pollution sources, improved waste and air emissions management and processing of marine debris/trash into reusable materials, theDOCK's presentation noted.</p>theDOCK team includes (left to right) Michal Hendel-Sufa, Head of Alliances, Noa Schuman, CMO, Nir Gartzman, Co-Founder & Managing Partner, and Hannan Carmeli, Co-Founder & Managing Partner.

<p>theDOCK's own portfolio includes companies like Orca AI, which uses an intelligent collision avoidance system to reduce the probability of oil or fuel spills, AiDock, which eliminates the use of paper by automating the customs clearance process, and DockTech, which uses depth "crowdsourcing" data to map riverbeds in real-time and optimize cargo loading, thereby reducing trips and fuel usage while also avoiding groundings.</p><p>"Oceans are a big opportunity primarily because they are just that – big!" theDOCK's Chief Marketing Officer Noa Schuman summarized. "As such, the magnitude of their criticality to the global ecosystem, the magnitude of pollution risk and the steps needed to overcome those challenges – are all huge."</p><p>There is hope that this wave of interest and investment in environmentally-positive maritime technologies will accelerate the blue economy and ESG investing even further, in Israel and beyond.</p>- 14 Countries Commit to Ocean Sustainability Initiative - EcoWatch ›
