- Precise counts of snake populations do not exist for many states and countries for two primary reasons:
-
- Most snake species are not considered endangered, so their populations are unmonitored.
-
- Snakes are notably difficult to detect and count.
Highlighted States
Alaska
Alaska is one of the two states that do not have any snakes. Snakes thrive in environments that are rocky and hilly and have some soil and heat. Alaska is devoid of places that are conducive for any snake species to survive. Although some states do not have native species of snake, they have been introduced into very small, contained environments. The state of Alaska does not have any area that will effectively grow any snakes. Even if a conservatory were to be opened in the state for some habitat or endangered species to be rehabilitated, it would cost the state too much to transform the location into a snake sanctuary. Even so, the species may not survive due to a lack of prey in the habitat.
This does not mean that Alaska is too cold for any life. Alaska contains some of the most impressive species of wildlife, plant life, and geographic marvels in the nation. For example, some of the fish and large mammals in the state are extremely large and make for great game and breeding purposes. The tough winter climate and lack of vegetation have made species hardier in order to endure extremely difficult conditions.
Hawaii
Hawaii is the second state that does not have snakes native to the environment, but there have been very few species introduced into the environment to enrich the biodiversity in the area. Most of the time, isolated land masses or those with extreme temperatures are not appropriate for snake species to survive. This does not mean that all island nations or states are devoid of any snake species, as many regions in the Pacific have an abundance of different species, including those that are venomous.
It is hard to appropriately describe exactly what a state with “no” snakes means. For example, Alaska is the only state that can truly be considered one without any snake species on its soils that are recorded. Up until very recently, this also included Hawaii - which is still number two on many lists. Another metric that can be used is whether there are any states with native snake species. If this is to be used, Maine could also be considered a state with “no” snakes, as there aren’t any species that are native there. With this being said, snake species often migrate or cohabit in certain areas, or are introduced by humans to enrich diversity or to preserve endangered species.
Texas
Texas, largely due to its climate and land mass, contains some of the most diverse ecosystems of serpents in America, and even the world. Of course, there are certain species of snake that prefer woodland areas, or even the large dense tropical jungles, but iconic species such as the rattlesnake have their home in Texas and many states that border it. There are over 65 species that are native and non-native to the area, as ecologists and zoologists often introduce other serpents to further diversify the gene pool or to save species altogether.
