This post is dedicated to the Bog Turtle, which is not an invasive species in North America but is actually an endangered species due to the invasive Purple Loosestrife and climate change. The Bog Turtle is one of North America’s smallest turtle species. They’re one of the rarest turtle species in the United States. Currently, they’re protected by laws that prohibit their capture or sale, but that doesn’t stop some individuals in the black market pet trade.
The fourth photo is of the invasive species Purple Loosestrife. This species is invasive in 48 states, similarly to Japanese Barberry, this plant was introduced for ornamental reasons. It is also speculated that the seeds were brought over from ocean ships, like the Spiny Water Flea. It is native to Europe and is found in Russia as well. Purple Loosestrife is able to adapt to a lot of different habitats, and like other invasive species it pushes out native plant species, harming biodiversity.
Bog Turtles have two known populations in the United State that are separated by 250 miles. Purple Loosestrife is impenetrable by the turtle, causing their habitat to be fragmented. This large of a distance between the two populations make it impossible for the two populations to mate, causing them to mate with their own small populations. This shows the threat of inbreeding. Along with habitat fragmentation, climate change is also posing a severe threat to the species. The Bog Turtle relies on its fragile habitat, which can be affected by erratic weather.
