Getting a New Perspective on the Great Lakes’ Water Quality

A watershed

The Great Lakes cover over 95,000 square miles and contain trillions of gallons of water. These vestiges of the last Ice Age define immense. But their greatness makes water quality monitoring difficult.

In 2010, Titus Seilheimer, a US Forest Service research ecologist at the time, led a project funded by the Great Lakes Restoration Initiative that parsed the vastness of the Great Lakes to estimate water quality in different basins. This information can identify which areas are likely to receive high nutrient inputs – which can cause harmful algae blooms and dead zones – and where resource managers should invest in restoration efforts.

How Do You Manage Collaborative Conservation Planning across 100 Million Acres? From a Bird’s Eye View, of Course!

The saying “The whole is greater than the sum of its parts” is often attributed to the Greek philosopher Aristotle, and that couldn’t be more true when it comes to doing conservation planning across 11 states, multiple federal agencies and millions of acres of public and private land.

The Sage Grouse Initiative (SGI), led by USDA’s Natural Resources Conservation Service (NRCS), introduces the SGI Interactive Web Application, a tool that will take habitat restoration efforts for sage grouse to new heights — both visually and on the ground. The tool graphically layers vital pieces of information to paint a more cohesive picture of connected landscapes, so state and federal agencies and their partners can make more effective and targeted decisions.

On the Map: The Land, Water and Conservation Fund

United States Forest Service LWCF projects and many other Government LWCF projects can be viewed in the new interactive map.

There is a Federal program that you may not have heard of, but it is responsible for conserving millions of acres of recreational and conservation lands for Americans to enjoy, and it helps fund local parks, provide access to rivers and trails, and preserve wildlife habitat in every state in the Union.  This program is the Land and Water Conservation Fund (LWCF) and each year, the Department of the Interior and Department of Agriculture request funding from Congress to support grants to states and high priority federal recreational and conservation investments. Locating and learning about these special places is now easier than ever through a new interactive map. The map enables everyone to explore the 173 public projects proposed for investment in 43 states, including important waterfowl nesting habitat in the Prairie Potholes, battlefields and historic sites from Pennsylvania to Washington, scenic vistas in iconic locations like Maine’s Acadia National Park, and recreation sites in national monuments in California and Arizona.

Land and Water Conservation funds secure access for the American public to their Federal lands.  For 50 years, the law has been one of the most successful programs for recreation and conservation in our history. LWCF has provided funding to local communities that supported the construction of more than 40,000 city parks, hiking and biking trails, and boat ramps, and access to thousands of acres of fishing and hunting and  important wildlife habitat.

Early-Season Forecast Shows Rain – Not Snow – Keeping Pacific Northwest Wet

Something about January’s water supply forecast confused me. Current condition maps of the Pacific Northwest are a discouraging spread of red dots, meaning the snowpack contains less than half the normal amount of water. But water supply forecasts for the same region predict normal streamflow in the spring and summer. How can that be? Less snow means less snowmelt, right? Well…maybe.

To rise above my simple, linear thinking, I met with Rashawn Tama with USDA’s National Water and Climate Center. Tama, a hydrologist and forecaster for USDA’s Natural Resources Conservation Service, produces forecasts for the Columbia River basin. His forecasts are built around prediction models that help transform tables of raw data into meaningful maps and colorful dots. Read more »

Mapping U.S. Agriculture

2012 Ag Census Web Maps tool helps you create a visual overview of data for U.S. farm demographics, economics, crops, and livestock.

2012 Ag Census Web Maps tool helps you create a visual overview of data for U.S. farm demographics, economics, crops, and livestock.

Agricultural data are valuable for analysis, and thanks to the Census of Agriculture and other surveys, NASS has plenty of data available. As a cartographer, however, I obviously prefer to present the data in map form. A map gives anyone a chance to visualize data for multiple geographic areas as a cohesive image, providing a graphic overview of the agricultural phenomena. It also allows map readers to visually compare regions, and discern patterns and relationships in the data across regions, topics, and time.

When it came to the ag census, for each of the past eight editions, NASS produced an atlas of thematic (statistical) maps illustrating various aspects of U.S. agriculture. While great for their time, with the evolution of digital technology, these paper maps are no longer sufficient on their own. The component missing from them is the data behind the maps, so what better way to depict and also convey a myriad of county-level statistics than through a web map application? Read more »

U.S. Forest Service Offers Winter Yurt, Cabin Adventures

While some may close up tents and winterize recreational vehicles this time of year, there are others who look forward to a winter filled with adventures on forests and grasslands. The draw is yurts and historic cabins available to rent that offer a bit of solitude for camping, a dose of adventure on skis, snowshoes or snowmobiles, and a lifetime of memories.

A yurt is a circular tent with canvas walls. There are many different styles and sizes of yurts, but generally each yurt is different in what it offers. Typically, you can expect to provide your own bedding, food, and cooking supplies. Some include beds, tables and chairs. Others have camp stoves and wood burning stoves. Check information on Recreation.gov before making your reservation and committing to a stay. Read more »
