“We see massive opportunities for our innovation, expertise, and culture to play a role in finding solutions to some of society’s biggest challenges.”
—Chuck Robbins, Chairman and CEO of Cisco
Cisco Systems (#64 on the Fortune 500 list) is a technology conglomerate that is known for its networking hardware, software, and telecommunication equipment. For those of you who work for large organizations, you may be all all too familiar with Cisco subsidiaries such as Webex and Jabber. And for those of you who don’t, you’ve probably heard of a thing called the internet … and it just so happens that 80 percent of the world’s web traffic currently travels securely across Cisco connections. In other words, Cisco Systems, and it’s 75,000 employees, plays a role in the day-to-day life for many of us and we may not even know it.
Another thing that we might not know about Cisco Systems is that the company consistently lands towards the top of the list in the various corporate sustainability rankings. Given the high marks that the company consistently receives from the sustainability community, I thought it would be worth checking out what Cisco is up to in the world of biodiversity conservation.
Like many sustainability leaders, Cisco is doing a lot of work to reduce greenhouse gases, leverage renewable energy sources, and adopt responsible sourcing and manufacturing practices. However, Cisco is also engaged in some interesting (at least to me!) small-scale efforts that have a positive impact on biodiversity and wildlife. In this week’s post, I’ll share two simple strategies that any company or homeowner can embrace. Next week, I’ll share a third biodiversity / wildlife conservation strategy that requires a bit more technology, something that Cisco has in spades.
Minimize impacts to local wildlife during breeding season
Many companies take steps to avoid certain types of operations or construction activities during the breeding season for birds and other animals in the area. This precaution helps prevent the destruction of active nests and reduces noise that can scare away or stress animals during the breeding season. In the case of Cisco Systems, several of the buildings at its San Jose, California headquarters are located near a protected area for American cliff swallows. To help protect American cliff swallow habitat during nesting season, Cisco closes its balconies on those buildings and doesn’t remove the mud nests until nesting season is over.
Easy right? Yes, this might be a small gesture, but it’s an indicator of the company’s desire to be a good corporate citizen. In the words of famed basketball player and coach John Wooden, “It’s the little details that are vital. Little things make big things happen.”
Wildlife corridors are often viewed as a useful tool to help maintain and restore biodiversity and wildlife populations on private and public land. A “wildlife corridor” is defined as any space that facilitates the movement of animals between core habitat fragments. The goal of a corridor is to maintain or improve the number and health of species in an area. This assumes that improving the connectivity of separate patches of a suitable habitat will allow isolated populations of animals to interbreed. Corridors may also help alleviate climate-change impacts on animal populations by enabling animals to move to a more suitable habitat as conditions change. From a human perspective, well-designed corridors help us avoid collisions that kill or injure wildlife and cause property damage and injury to humans.
The importance of wildlife corridors is perhaps best illustrated with an example of large carnivores, such as bears or mountain lions, which require large home ranges for food, den sites, and other needs. To maintain a sustainable population of 50 to 70 mountain lions, we need a minimum of 3,120 square miles; to maintain a sustainable population of 200 black bears, we need at least 780 square miles.
These large habitat requirements are significantly larger than most protected areas in the United States, and that’s where corridors can help. Corridors can link large patches of habitat and enable these large carnivores to move from one patch of habitat to another and support a sustainable population of these animals. We could also consider the option of having a smaller population of mountain lions or bears in a certain area, but such small populations of either species are unlikely to be sustainable in the long term.
Corridors come in a wide variety of shapes and sizes. Some corridors take the form of linear patches of land that directly connect two patches of habitat. Other corridors are irregular-shaped stepping stones of land that enable species to move from one patch of habitat to another, even when these stepping stones are not directly connected to the core patches of habitat. Corridors may be man-made, such as underpass tunnels or overpass bridges across a roadway, or they may take the form of natural corridors, such as rivers and mountain ranges.
Some corridors are designed with a regional scale in mind, such as a corridor that facilitates bird and butterfly migration from Canada to Mexico. Other corridors are designed at a local level, perhaps connecting local wetlands to help sustain populations of reptile or amphibian species. That’s where our second Cisco Systems example comes in. Cisco created three turtle tunnels under the highway at its Boxborough, Massachusetts location to provide safe passage for the migration of Blanding’s turtles and eastern box turtles, listed as International Union for Conservation of Nature and Natural Resources (IUCN) Endangered Species and IUCN Vulnerable Species, respectively. Cisco also installed curbing around the site to prevent migrating turtles from entering the roadway and parking areas.
We can design corridors that are intended to be used for brief periods to support seasonal migrations or the dispersal of young animals, or we can design corridors that are intended to be used on a permanent basis. Some species of plants, reptiles, and insects may even spend their entire lives in the corridor habitat.
This brings us to an important point. We’ve all heard the saying, “Beauty is in the eye of the beholder”, not to be confused with a similar truth that some of us might have “heard” in college: “Beauty is in the eye of the beer holder”. But I digress. This beauty perception concept also applies to corridors. A corridor that is attractive to one species may be a barrier to another (e.g., a corridor that is appealing to a coyote may not be appealing to a bear, amphibian, otter, or butterfly). It’s important to be clear on the target species that the corridor is intended to help before choosing a corridor design. Cisco focused on creating a corridor that was specific for Blanding’s turtles and eastern box turtles. Similarly, you might think of ways to support specific species in your area to help them move between core habitat fragments.
Next week, we’ll continue this discussion as we look at a third strategy that Cisco uses to protect wildlife and biodiversity. Hope to see you then!
