Grand Canyon is one of the iconic and breathtaking natural wonders that people across the world yearn to see. Over 1,500 species of plants and 400 species of animals live in the Grand Canyon, making it one of the most biodiverse places in the country. There's no denying that the canyon's iconic landscapes demand attention, but it's equally important to recognize the biodiversity that thrives within.
There are five major ecosystems in the Grand Canyon, including the Riparian ecosystem, desert scrub, pinyon-juniper woodland, ponderosa pine forest, and mixed conifer forest.
Let's take an in-depth look at these 5 ecosystems:
The Riparian Ecosystem
Found along the banks of the Colorado River at the bottom of the canyon, the Riparian ecosystem is characterized by dense vegetation, including cottonwood trees, willows, and sycamores. Additionally, this ecosystem can also be found near small creeks or springs around the Grand Canyon, regardless of elevation.
The Desert Scrub Ecosystem
The desert scrub ecosystem is located at very low elevations, and before its discovery, all the water from higher elevations had evaporated. This ecosystem is known as one of the hottest and driest of the five Grand Canyon ecosystems.
The Pinyon-Juniper Woodland Ecosystem
This ecosystem is found in sunny areas below the North and South rims. It receives approximately half as much rainfall as the Ponderosa Pine Forest and features drought-resistant plants. The Pinyon-Juniper Woodland ecosystem is situated at mid-elevations within the canyon and is characterized by pine and juniper trees.
The Ponderosa Pine Forest Ecosystem
This ecosystem is discovered at higher elevations within the canyon, present on both the South and North Rims. Despite averaging five feet of snowfall per year, it experiences intense thunderstorms that can lead to flash floods during the summer.
The Mixed Conifer Forest
This ecosystem is found at the highest elevations in the canyon and is also known as the boreal forest ecosystem, located at the North Rim, between 8,200-9,200 feet. This ecosystem receives more rainfall compared to any other ecosystem in the Grand Canyon.
