Pinyon jays present both a conservation challenge and a paradox. While the species has declined, its preferred habitat (pinyon-juniper woodlands) has expanded, and in some areas to a large extent. It seems that population declines are not a function of reductions in habitat amount, but are related to changes in habitat quality. Up to now research on the species has been paltry,
and so details about the trend have only recently begun to surface.

Recently published research can help land managers to identify important hubs and pathways of genetic connectivity for greater sage-grouse. This knowledge can be used in evaluating proposed development or management actions in terms of how they could disrupt, protect or restore critical places of conservation for greater sage-grouse habitat. The genetic evaluation technique, combined with mapping technology, can be used to evaluate land management decisions in terms of their effect on more than 350 species that live in North American sagebrush habitat.

This study used historical and projected weather to predict changes in landscape composition and structure under two different climates, three restoration strategies, and two different fire management scenarios. They found that, without active restoration treatments, whitebark pine cannot survive. Management intervention actions such as planting rust-resistant seedlings and employing proactive restoration treatments, can return whitebark pine to some high mountain settings in western North America to create resilient upper subalpine forests for the future.

This study introduces a number of newer concepts and methods related to transboundary risk governance for the state of Arizona. The methods fill a gap in existing risk assessment efforts by explicitly identifying transboundary exposure. We show how the methods and results can be used to better define the scale of risk and design effective risk governance institutions. Improving scale recognition within existing transboundary risk governance systems can help reduce inefficiencies in risk planning.

The Western Governors’ Association (WGA) has addressed this need by surveying invasive species coordinators in WGA member states and territories Top 50 Invasive Species in the West to develop the “Top 50 Invasive Species in the West.” The compilation of terrestrial and aquatic invasive species includes highly-publicized examples such as cheatgrass, Quagga Mussels, tamarisk and the Emerald Ash Borer. The list also encompasses less well known, but still impactful, examples such as leafy spurge, Red shiner, Russian knapweed, and Golden algae.

Smoke from wildfires is a public health concern. Smoke affected the entire Pacific Northwest region in 2015, and again in 2017. Scientists developed the BlueSky Modeling Framework that forecasts where smoke will travel, allowing public health agencies and communities to prepare for smoke impacts. Wildfires are here to stay. Scientists predict that with climate change, the annual area burned will continue to increase. Learning to coexist with wildfire means we will have to learn to coexist with some amount of smoke.
Large wildfires have dominated the news in much of the western U.S. this past summer. Conservancy scientists working in rangelands and forests are engaged in many efforts to understand, cope with or avoid the effects of these fires. In fact, one Conservancy field crew working in the Northern Great Basin Experimental Range (NGBER) was chased from their beds and field work by one of these fires for a few days. They were collecting data on novel restoration approaches to reduce the vulnerability of sagebrush habitat to large wildfires beforehand and recover more successfully after the fires. This involved replacing one of the key culprits contributing to wildfires in the west, cheatgrass, with native plant species.

This report concerns a small facet of the JFSP-funded MASTIDON study in which summaries of the physical and chemical fuel properties of the sampled masticated fuelbeds were presented and the relationships of these properties to fuel age were explored. The scientist documented masticated fuelbed characteristics and correlated these characteristics to fuelbed age for ponderosa pine and mixed conifer stands of the US Rocky Mountains that were masticated using four techniques.

Managing wildfire for resource benefits and ecological purposes refers to a strategic choice to use naturally ignited fires to achieve resource management objectives.
