Therefore, these safety concerns should not be dismissed entirely, but rather be placed into the proper perspective. Likewise, vegetative succession, which is a natural transition of plant communities from earlier, more open canopies to more closed canopies, has greatly affected the quality of the living and reproductive habitats for both species, but the massasauga especially. So why are rattlesnake species in many areas having a hard time keeping up with the threats. This is where an array of many different homeowners, property owners, land managers, biologists and researchers, wildlife conservationists, and other stakeholders can collaborate and all work together to help secure these widely feared and misunderstood animal’s futures in the state of Wisconsin, especially for future generations who may very well not be as fortunate to see or observe these species in Wisconsin. not approach a fire, and the latter always give warning before they bite.
