Hidden like fish eggs in the streambed, the answer was buried in the mathematical models of Morgan Spark's graduate work. Biologists and land managers know early fish life is sensitive, and nature is difficult to predict. In the streambed, eggs and young fish can be at risk from unintentional habitat disruptions from activities such as grazing, prescribed fire, and road work. The question was how to know when wild fish are hatching and emerging to avoid those sensitive windows. A new tool, hatchR, is here to lend biologists a helping hand - or fin.

Did you know your cellphone's GPS locations can help us decipher how recreationists and wildlife overlap in time and space? Mark Ditmer, a research ecologist at the Rocky Mountain Research Station, and colleagues harnessed this cellphone-derived human mobility data to explore how managers can enhance recreation and protect wildlife in sensitive habitats.

For homeowners living in the wildland-urban interface, wildfire outreach programs encourage wildfire risk mitigation and evacuation preparedness as steps to protect homes and lives in the event of a wildfire. Wildfire risk mitigation may include activities such as removing vegetation from around structures and storing combustible materials (e.g. firewood or propane tanks) away from homes. Signing up to receive evacuation notifications, packing a to-go bag, or identifying evacuation routes are examples of evacuation preparedness. Music courtesy of Souvenir Thread.

Public lands provide extensive recreation opportunities for activities including camping and cabins, biking, horseback riding, hiking, and fishing. Due to increasing visitation and the associated impacts to natural resources and the visitor experience, recreation managers may decide to adopt a recreation allocation strategy to limit the number of visitors at a given time. Allocation includes allotment (splitting between groups such as commercial use and private use) and rationing (a mechanism for allocating within groups). The main strategies used for rationing include first come, first served, pricing, reservations, lotteries, and merit.

To effectively manage fire, land and fire managers need detailed, current local information - for example, the amount of burnable material present, fuel moisture levels, winds, temperatures, and terrain changes across time and space. Managers also need these data to decide where, when, and how to treat a landscape while balancing costs and benefits, projected wildfire risk, and potential impacts.

Until recently, wildlife habitat maps were static documents that can quickly become outdated anytime landscape conditions changed due to disturbances like wildfire, drought, and timber harvest. But now, researchers at the Rocky Mountain Research Station and their collaborators have developed an approach for producing near-real-time wildlife habitat maps using Google Earth Engine. These products are called Living Maps because of their ability to stay up to date - incorporating new input data and remaining accurate over time - thus functioning like an automated wildlife habitat monitoring system.

It's no secret that wildland fires kill trees, but are more trees killed by fire when they are already stressed from drought? New research from the U.S. Department of Agriculture, Forest Service indicates that prefire drought can increase tree mortality after fire, even with the same level of tree damage.

When smoke from a prescribed fire pops up on an otherwise clear day, people may question the rationale behind the haze. After all, smoke from wildland fires can be a major health hazard due to fine particulates (PM2.5) and gaseous pollutants. At the same time, prescribed fires are one of our best tools to reduce hazardous fuels and restore fire-prone forests and grasslands. In recent years, land managers have been asked to expand the use of prescribed fire, but smoke is consistently cited as a barrier. New research by USDA Forest Service scientists sheds light on one key smoke challenge - long-term smoldering of decomposed organic matter, also known as duff. Music courtesy of Souvenir Thread.

The desert is hot, dry, and prickly … the perfect combination for wildfires. So, shouldn't desert plants be used to fire? It turns out that Sonoran desert scrub communities, home to the iconic saguaro cactus, are vulnerable to frequent large or severe wildfires and may not recover for centuries, if at all. Recent publications by Rocky Mountain Research Station ecologists discuss how desert plants respond to fires, and how big, how often, and how hot fires burn in this ecosystem. The Fire Regime Synthesis about Sonoran desert scrub communities and associated Species Reviews are published in the Fire Effects Information System (FEIS) - an online searchable database of research syntheses about how fire affects ecosystems and individual species.

In a field that is hyper-focused on efficiency and cost savings, environmental DNA (eDNA) sampling - or detecting fish and wildlife from traces of genetic material in the environment - has become the gold standard. Over the last decade, eDNA sampling has emerged as a powerful and cost-effective tool for national forests to obtain the data they need to make management decisions. Now, Forest Service scientists have created "biochips" that generate these high-value data even more efficiently, buoying the value of eDNA monitoring capacity far into the future.

In forests across the western United States, large, severe wildfires are creating treeless patches that are unlikely to reforest naturally due to a lack of seed sources and a warming climate. Active reforestation through tree planting has the potential to help forest ecosystems recover after wildfire. Music courtesy of Souvenir Thread.

Historical and contemporary policies and practices, including the suppression of lightning-ignited fires and the removal of intentional fires ignited by Indigenous peoples, have resulted in over a century of fire exclusion across many of the USA's landscapes. Within many designated wilderness areas, this intentional exclusion of fire has clearly altered ecological processes and thus constitutes a fundamental and ubiquitous act of trammeling. Through a framework that recognizes four orders of trammeling, we demonstrate the substantial, long-term, and negative effects of fire exclusion on the natural conditions of fire-adapted wilderness ecosystems. In order to untrammel more than a century of fire exclusion, the implementation of active programs of intentional burning may be necessary across some wilderness landscapes. We also suggest greater recognition and accommodation of Indigenous cultural burning, a practice which Tribes used to shape and maintain many fire-adapted landscapes for thousands of years before Euro-American colonization, including landscapes today designated as wilderness. Human-ignited fire may be critical to restoring the natural character of fire-adapted wilderness landscapes and can also support ecocultural restoration efforts sought by Indigenous peoples.

What plants can survive fire, can displace native plants, and are difficult to manage? Among others are these eight nonnative species in the western United States: buffelgrass, cutleaf blackberry, diffuse knapweed, Himalayan blackberry, Sahara mustard, spotted knapweed, ventenata, and yellow starthistle. Unfortunately, one of the reasons that invasive plants are so hard to manage is because there is no one-size-fits-all approach—each species has its own tricks enabling it to thrive and wreak havoc.
