Southwestern Willow Flycatcher, Other Species Benefit from Riparian Restoration Work in Utah

Jim Hook, owner of the Recapture Lodge and volunteer firefighter in Bluff, Utah, has been working for years to manage and restore the riparian habitat on his property along the San Juan River in southeast Utah.

Where the Cottonwood Creek and the San Juan River meet, Hook is working with USDA’s Natural Resources Conservation Service (NRCS) to establish healthy riparian habitat. His hard work over the years has begun to yield results as the invasive plants have begun to die and native plants are taking their place. An endangered bird species, the Southwestern willow flycatcher, is one of the species that will benefit from his restoration work.

Wyoming Landowners Restore Riparian Areas in Big Horn Basin

It took Dee Hillberry six years before he could get a handle on encroaching and hardy invasive vegetation. Working on two separate properties, he removed tamarisk trees, or salt cedars, from 200 acres along Cottonwood Creek and Russian olive trees from 100 acres along the Big Horn River.

Despite Hillberry’s hard work in Hot Springs County, Wyoming, his efforts in restoring riparian areas were part of a larger endeavor that involved work done in phases over several years, over hundreds of miles, and with numerous partners in the Big Horn River basin. The basin is about 100 miles wide, and so far, more than 13,000 acres of invasive trees have been removed from the riparian area.

Inner City Youth Protect an Ancient Oregon Forest Wilderness

Inner city youth helped protect an ancient forest wilderness in the Siuslaw National Forest by spending a day removing invasive tansy ragwort.

High school students from the Inner City Youth Institute  in Portland, Oregon, arrived in the Drift Creek Wilderness near the Alsea River, where Douglas fir and western hemlock make up the largest stand of old-growth rainforest in the Oregon Coast Range.

“We love coming to the Siuslaw,” said institute group leader, Stacey Sowders. “We love this chance to do meaningful work and meet people who are so passionate about what they do.”

Why is Cogongrass So Successful at Invading the South?

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from the USDA’s rich science and research portfolio.

Cogongrass makes kudzu look like a lightweight. A perennial grass, it grows on every continent except Antarctica and has earned a reputation as one of the worst weeds on Earth. In the South, cogongrass ranks among the top 10 plant marauders, invading forests, rights-of-way, and agricultural fields, literally taking over the landscape and altering ecosystems.

Native to Southeast Asia, the weed first arrived in the United States in 1912 as packing material in orange crates imported to Grand Bay, Alabama.  A few years later, farmers planted cogongrass in Mississippi as a possible forage crop. Since then, it’s spread to more than 66,000 acres throughout the South, its progress limited only by winter cold. Landowners and agencies have fought this weed for years with limited success.

Conservation Work Restores Habitat for At-Risk Wildlife and Plants on Hawaiian Island

The Molokai Land Trust (MLT) is a partner of USDA’s Natural Resources Conservation Service in its efforts to restore native landscapes on the Island of Molokai in Hawaii. MLT and NRCS have partnered together on many projects, including the one highlighted in this post. Justin Fritscher, NRCS.

The endangered wedge-tailed shearwater and other at-risk plant and wildlife species find sanctuary in the coastal dune ecosystem of Hawaii. But like many native ecosystems in the state, this one suffers from the effects of human development and invasive plants and animals.

In an effort to restore ecosystems in the region, the Molokai Land Trust, or MLT, on the Island of Molokai, is working to restore and replant native vegetation and remove threats from invasive species.

Eat It to Beat It - 2014 Garlic Mustard Challenge

Spring is often associated with ramps, rain, flowers and frogs, but on the Monongahela National Forest, the season of rebirth is focused on protecting our woods from garlic mustard.

Garlic mustard is a non-native invasive plant first brought to America by European settlers in the 1800s. They enjoyed eating it because of its zesty garlic-like flavor. They just had no idea that this plant would become one of the biggest threats to the diversity of plants and animals found in our eastern forests.

In an effort to fight the spread of this invasive species, the Monongahela, along with several partners, hosts an annual Garlic Mustard Challenge to increase public awareness about the threat of non-native invasive species and to achieve boots-on-the-ground results.  Last year, elementary school students in Grant County, West Virginia, removed more than 13,000 pounds of garlic mustard from the Monongahela.

Small Farmers Share Land, a High Tunnel and Knowledge

When Jim and Nancy Faulkner bought their small farm in Boxborough, Mass. in 2009, the place was a mess. Buildings were falling down, the soil was poor and the land was covered with invasive plants. Nonetheless, they wanted to turn it into a sustainable farm.

Help came from two very different directions: a government agency and another small farmer.

“I really needed a farm plan,” said Jim Faulkner, who wanted to ensure he complied with town bylaws. “I wanted to show that I was serious and that I had a plan.”

It's National Wildflower Week! Get a Little Wild with Flowers on National Forests and Grasslands

Walking along the peaceful Hunter Creek Road in the Charles C. Deam Wilderness, in the Hoosier National Forest, you catch a glimpse of beautiful periwinkle flowers swaying in the warm spring air. A short hike uphill and you are immersed in the full bloom of wild hyacinth, along with other delightful wildflowers such as twinleaf and trout lily.

While getting caught up in the beauty and serenity of this colorful scene, you may observe a white-tailed deer, raccoon, fox squirrel, red-shouldered hawk or scarlet tanager. This enchanted corner of the Hoosier National Forest is its only congressionally designated wilderness. It boasts plentiful spring flora thanks to its proximity to a geologic feature known as the Mount Carmel Fault. And, this is just one of 82 Wildflower Viewing Areas in the Forest Service’s Eastern Region

Montana Seed Growers "Sow" Importance of Organic Farming

When Anna Jones-Crabtree and Doug Crabtree founded Vilicus Farms in 2009, they snagged the farm’s name from Latin, as “vilicus” means steward. Anna and Doug are definitely stewards of their 1,200-acre organic farm near Havre, Mont.

In a region where wheat is the primary crop and stretches as far as the eye can see, Vilicus Farms is unique. They work on a five-year rotation of about 15 different crops, including flax, lentils, oats, red spring wheat, durum, sweet clover, vetch, peas, rye, winter wheat, buckwheat, safflower, sunflower, spring peas and chickling vetch.

The farm is divided into strips about one mile long and 240 feet wide, and the Crabtrees grow one crop in each strip. Between the strips are untilled sections of native grazing land that serve as buffers to catch snow in the winter for added moisture.

Celebrate Fall Season With Free Access to Public Lands on Sept. 28

The crisp fall air provides an invigorating environment for outdoor activity.  What better time to visit and volunteer on our national forests and grasslands than on Sept. 28, for the 20th annual National Public Lands Day and second annual National Tribal Lands Day. This is the nation's largest, single-day volunteer effort for public lands sponsored by the National Environmental Education Foundation. This year’s theme is: “Helping Hands for America’s Lands.”

National Public Lands Day is one of six fee-free days in honor of Martin Luther King Jr. Day, National Get Outdoors Day, and Veterans Day Weekend. Fees are waived generally for day use, such as picnic areas, developed trailheads and destination visitor centers. Fees are not waived for concessionaire-operated facilities or for overnight use such as camping or recreation rentals.
