Extended Discussion on Forestry as well as Species that Once Existed
Massive forest fires are prevalent primarily because forests have been slashed, and ground clutter has not been cleared. This neglect allows the ground clutter to dry out, making it highly unstable and flammable. As a result, various species have gone extinct in different regions worldwide. For instance, beavers have locally gone extinct in Wisconsin, which is detrimental to the environment since beavers are a keystone species that create wetland refuges for wildlife.
When a forest is destroyed, a process called succession occurs, where it initially transforms into shrubland, which is then colonized by forest species. This is followed by the growth of young, fast-growing trees, and eventually, slower-growing hardwood trees. This process is crucial; if a fire occurs, having a diverse ecosystem allows for recovery. However, if an area remains in a disturbed state without recovery, it can reach an alternative stable state, preventing it from returning to its original form.
Certain plants, such as osage oranges, pawpaws, and avocados, used to be spread by giant ground sloths. However, after these ground sloths went extinct around 30,000 years ago, around the time humans first arrived in North America, these plants lost their primary means of distribution. Instead, deer and other animals have tried to fill this role. In areas where deer populations are high and predators are absent, such as wolves, which have been largely eradicated in the eastern states by hunters seeking to protect their cattle, the problem intensifies.
Regarding deer ticks, an increase in deer leads to a higher prevalence of Lyme disease. Conversely, fewer squirrels and white-footed mice result in fewer deer ticks reaching adulthood, consequently reducing the risk of Lyme disease transmission to humans and deer. Originally, the passenger pigeon occupied the ecological niche now filled by small arboreal animals that consume tree nuts and seeds. Passenger pigeons helped control tick populations because they would eat the ticks and could fly away, unlike squirrels and mice, which remain vulnerable to becoming targets for deer ticks.
