Climate change has produced a number of threats to wildlife throughout our parks. Rising temperatures lower many species survival rates due to changes that pb to less food, less successful reproduction, and interfering with the surroundings for native wildlife. These detrimental changes are already apparent in our National Upper-case letter Area parks.

Ascension Temperatures and Invasive Species

Rising temperatures gamble destabilizing the residue between wildlife and their ecosystem. Every bit plants adapt to changing warming patterns, usually by blooming earlier or shifting to cooler locations, the wildlife that has adapted to them will be forced to face new environments.

Some species will struggle to find nutritious plenty food to fit their existing gut biomes. Pollinators, for instance, must feed from flowers that are blooming earlier in the year. Other animals may detect their habitats are no longer able to support their biological science.

However, it is also possible that some animals will exercise ameliorate in a warmer climate. Those species volition outcompete others, expanding their own territory and food sources. But not all wildlife belong where they flourish. When species adapted to their environments lose their natural advantages, that leaves room for invasive species to multiply in the changing environment. Emerald Ash Borers and Gypsy Moths are examples of invasive species commonly found in the National Capital Region that have devastated native communities.

Brook trout in the Catoctin Mountain Park offer a clear instance of how climate modify furnishings interact with invasive species spread. The brook trout is a freshwater fish species native to eastern N America, and it requires cold, clear stream habitats. Competing with the brook trout are nonnative brownish trout which tin tolerate college temperatures.

Increases in air temperature are warming aquatic habitats, leading to an overall decrease in brook trout and giving the survival advantage to the invasive brown trout. A 2017 study from the US Geological Survey establish that brook trout are capable of adapting and foraging for food in warmer waters only not when they're competing confronting brown trout.

Flooding and Loss of Habitats

Increased precipitation from climate change is contributing to more frequent and extreme weather events such as flooding. The college frequency of flooding has detrimental effects on wildlife because they can destroy cardinal pieces of ecosystems and habitats.

At that place is the obvious destructive effect that floods have on the environment—such as flooded land and burned forests—merely they also have other lasting effects like astringent water pollution. Speedy flood waters spend little time in a purification place (similar in the footing or in a wetland) and so the surface flow doesn't lose the soil particulates pollutants it has picked up. Their speed too erodes streambanks and soil surface. New locations of continuing water can drown tree roots, also.

Forest Thrush Migration

The wood thrush is the official bird of Washington, DC, and tin can be found in Rock Creek Park, only changes in climate may eliminate their regional population within the century. In addition to altering this songbird'southward DC habitat and food sources, climatic change negatively interferes with the wood thrush's lengthy migration from Cardinal America.

Wood thrushes fly up from the tropical forests of Central America every summer to their northern convenance grounds, anywhere from Florida to Maine. They demand undecayed ripe fruit and insect populations to fuel their journeying, which may non be available as the climate warms. Furthermore, their usual breeding grounds are growing warmer, meaning they lose habitable areas and must fly farther north.
