Managing Forests in the Face of Drought – There is Help!

Drought, especially prolonged or severe drought, can be a major stress in forest ecosystems.  Drought can kill trees directly or indirectly through insect attack or wildfire. Both of which are more likely to occur during drought.

Tree mortality impacts most of the ecosystem services provided by forests, including the amount of wood that grows, how much carbon is captured and stored, the health of critical wildlife habitat, water yield and quality, and even whether it’s safe to pursue recreational activities such as hiking or hunting.

Oregon Conservation Groups Partner with USDA for Results

Ralph Duyck on the Tualatin River Watershed

Ralph Duyck is one of 42 landowners who used the Conservation Reserve Enhancement Program (CREP) to protect the Tualatin River Watershed. With the initial goal of restoring fish habitat and cooling the stream, Duyck also noticed an increase in wildlife on his property.

A small group of conservation enthusiasts gathered at Ralph Duyck’s farm near Forest Grove, Oregon with a shared goal. They wanted to protect water quality and fish and wildlife habitat in and around the Tualatin River, an 83-mile tributary of the Willamette River that runs through Portland.

The group didn’t know how much interest they could attract or how much they could achieve—but that was 2005. Today, the Tualatin Basin Partners for Clean Water’s membership includes more than a dozen cities, counties, conservation districts, and environmental groups. Read more »

Giant Sequoia Trees Face “Drying” Times

“A mature Giant Sequoia can use 500-800 gallons of water every day during the summer,” said Anthony Ambrose, a tree biologist at U.C. Berkeley. “That’s a lot of water necessary for just one tree.”

For the first time in at least 125 years, Giant Sequoias in the southern Sierra Nevada Mountains of California are showing significant amounts of “dieback” in their foliage due to several years of drought. Read more »

SBIR Grantee’s Response to Killer Beetles: SPLAT!

The Small Business Innovation Research (SBIR) program at USDA offers competitively awarded grants to qualified small businesses to support high quality, advanced concepts research related to important scientific problems and opportunities in agriculture that could lead to significant public benefits.  The National Institute of Food and Agriculture (NIFA) administers SBIR Phase I grants that are limited to $100,000 and a duration of 8 months, and Phase II grants of up to $500,000 and 24 months that are open only to Phase I awardees. Below is the first-hand account of NIFA-funded SBIR research from Agenor Mafra-Neto, President and CEO of ISCA Technologies, Inc.

It might sound like the subject of the lamest B-horror flick ever made, but for pine trees in western North America, it’s a true story—the plant world’s equivalent of a zombie plague that has destroyed an estimated 723 million cubic of timber on more than 17.5 million hectares of forested land.

All on account of a tiny mountain pine beetle (MPB), no larger than a single grain of rice. Read more »

Oh Maple Syrup, How I Love Thee. Let me Count the Ways.

Okay, yes it’s Maple Syrup Day, an unofficial holiday, but the day allows us to celebrate and recognize this often underrated commodity. So in honor of this lovely product, here are some interesting tidbits that you may not know.

I use maple syrup on many things; not just pancakes, waffles and French toast, but also in recipes like soups and casseroles, to sweeten granola or oatmeal, even coffee. I’ve used it on ice cream and even snow, on salads and in salad dressings. My own step-father is known to take a shot of maple syrup every now-and-then. It is delightful on its own. Maple syrup can also be used to make maple cream, maple sugar, and maple candy. Read more »

Saving Our Forest Heritage in a Vault

Trees are often referred to as the lungs of the earth, providing not only the oxygen we need to breathe but a filter to clean our air and water. Trees from forested lands provide timber for our homes, food for people and wildlife, protection from weather extremes and, in urban and rural settings, beautify cities and landscapes alike.

As the largest steward of forested lands in the nation, the U.S. Forest Service works to protect and enhance forest resources not only on National Forests, but on all the Nation’s forests. Our agency puts a lot of effort into safeguarding trees where they grow, but trees are increasingly at risk from fire, changes in climate, insects, diseases and development. Read more »
