Plant identification

Restore overgrazed lands

Volunteers help restore lands and waters in areas impacted by livestock grazing. We pull weeds, protect springs, and plant native species. Join us in the field ›

Work with partners

We team up ranchers, agencies, researchers, and others to minimize grazing pressure on the ground. Learn about our work as a grazing permitee on the North Rim Ranches.


Advocate for the land

Nearly all of our public lands are open to grazing. We plug into every management process we can to advocate for less grazing across the plateau.

Native plants - what and why

Native plants - what and why
Andry Zharkikh

What are native plants, and why do they matter?

Native plants occur naturally and have evolved to the specific locales in which they grow. They attract colorful arrays of butterflies and bees, provide food and cover for voles, harrier chicks, fawns, and other animals, and help cool the water in streams. Native plants are important components of healthy and balanced natural areas.

Native plants and grazing

On the Colorado Plateau, where rocks outnumber plants, the ground is dry, and water sources scarce, livestock leave big impacts on the land. Native plants wither under the pressure of too many mouths and hooves. We work with ranchers, land managers, and others to study grazing impacts, address problems, and advocate for better grazing policies and management of our public lands.

Collecting data on grazing impacts

Fences are just as good at keeping animals out as they are at keeping them in. We use reference areas, which were once heavily grazed, to track the recovery of native species when cattle, deer, elk, and sheep are fenced out. We study the variety of plants that replace non-natives, and count how many of each species we find.

Identifying native plants

Pulling weeds

With the help of our herculean volunteers, we remove invasive plants in reference areas across the plateau. Eliminating weed seeds is critical to reverse the trend of invasives, and after years of persistent weeding efforts, we've seen significant decline of non-native species and a glimpse of what healthy public lands could look like.

Grazing - why care

Why care about grazing on our public lands

In the Southwest, cows aren’t grazing in green, bucolic pastures. They roam around parched lands and marginal forests looking for scarce food and even scarcer water. They damage biological soil crusts, erode streambeds, and crush native plants.


Grazing - where cows don't graze

How widespread is cattle grazing on the Colorado Plateau?

We know that cattle graze on the majority of our public lands, but pinning down an exact number is no easy task. We're compiling data from the four Colorado Plateau states — Arizona, Utah, New Mexico, and Colorado — to determine just how widespread cattle grazing is on the Colorado Plateau.

Grazing - North Rim ranches

North Rim Ranches

In 2005, the Trust bought grazing permits on 830,000 acres of public lands north of the Grand Canyon. We work with a ranching family to manage the day-to-day operations of North Rim Ranches. Historically overgrazed, it's the perfect grounds to study and test conservation-based livestock management. Read on ›

For 20 years, a landmark deal between ranchers and conservationists protected spectacular side canyons along the Escalante River in Grand Staircase-Escalante National Monument. Now, many have been reopened to grazing. Learn more ›


Grazing -Breaking down the system (intro)

The West's grazing system explained

Public lands, by definition, are open to everyone for a variety of uses. Livestock grazing is the most widespread, as it's promoted and subsidized by federal agencies. Here's how grazing works in the West.

Grazing - grazing explained (text)

Note: when we talk about grazing, we’re talking about livestock — primarily cattle and sheep.

(Game animals, like elk and deer, can contribute to problems related to overgrazing if overpopulated.)

The grazing system in the West is based on a law from the 1930s called the Taylor Grazing Act. It divides millions of acres of public land in “grazing districts,” which are further segmented into “allotments.” Ranchers can apply for permits from the Forest Service and Bureau of Land Management to graze livestock on these allotments at a very low cost. Federal grazing fees are currently $1.41 per animal unit month (AUM), an obscure unit of measurement (see jargon list below) that basically means:

It costs $1.41 per cow/calf pair, per month, to graze on public lands. So if you have 100 cows, it costs you $1,692 to graze your herd on public lands for a year.

States in the Four Corners region charge six to 13 times more to graze on state lands. The formula that determines federal grazing fees is more than 40 years old and doesn't even account for inflation. By subsidizing grazing, the federal government is relying on the public to foot the bill of public lands ranching in the West.

Grazing - dictionary

Grazing dictionary

Graze: to eat small portions of food throughout the day

Jargon abounds in the grazing world. Let's break it down:

Allotment: An area of land that ranchers are permited to use to graze their livestock

Exclosures: These are fenced reference areas free of grazing animals that scientists and land managers use to see how the land recovers in the absence of cattle.

Forage: Edible plants that grazing animals eat (example: grasses)

Utilization: This number, often expressed as a percent, describes the amount of plant material that livestock eat compared to how much is available.

Animal unit month (AUM): An AUM is how much food a 1,000 pound cow and a calf (or one horse or 5 sheep) eat in a month.
