Tackifiers are long‐chain carbon compounds used for soil stabilization and hydroseeding and could provide a vehicle for biological soil crust restoration. We examined the sensitivity of two dryland mosses, Bryum argenteum and Syntrichia ruralis, to three common tackifiers- guar, psyllium, and polyacrylamide (PAM) for erosion control and revegetation. When compared to water, guar tended to decrease growth, psyllium tended to increase growth, and PAM’s effects were generally neutral to positive. Within tackifier types, increasing concentrations of guar tended to decrease growth, while increasing concentrations of psyllium tended to increase growth. Changes in PAM concentrations had little effect on growth. Increases in guar and psyllium lowered pH and increased P and K. Psyllium and PAM yielded promising results as potential agents of dispersal and adherence of dryland mosses in field restoration.

Description: During this session, USDA Forest Service and collaborative members will explore lessons learned in the first 10 years of CFLRP monitoring – what worked well and what challenges we continue to encounter in the multi-party monitoring of ecological, social, and economic effects. Given those lessons, we will then discuss where we go from here.
Presenters: Tom DeMeo, Regional Ecologist, Pacific Northwest Region, USDA Forest Service; Jessica Robertson, Integrated Restoration Coordinator, USDA Forest Service; CFLRP project practitioners

During the 2011-to-2021 study period, increases in the number of days of heavy smoke were observed in communities representing 87.3% of the US population, with notably large increases in communities characterized by racial or ethnic minority status, limited English proficiency, lower educational attainment, and crowded housing conditions.

The best seed sources for restoration of Elymus elymoides in invaded sites were populations with longer roots, larger seeds and earlier emergence. These easily measured traits were strong predictors of survival in disturbed field sites. While the most successful populations were found in areas with similar abiotic conditions as planting sites, there was phenotypic variation even among populations originating from locations with similar conditions. Thus, our results indicate that abiotic conditions are important considerations when selecting seeds, but these conditions may not sufficiently predict which populations will establish. Understanding population differences in seedling functional traits can improve predictions of restoration success.

Description: PTSD is quietly impacting wildland firefighters with its often devastating personal and professional repercussions. While no official numbers exist, suicide has become another statistic now necessary to track within the wildland community as anecdotal data show an alarming trend. While agency’s come to grips with this burgeoning problem, firefighters can educate themselves to better understand the dynamics of stress, trauma and PTSD. This event will provide a unique view of the insidious nature of trauma, its effects on the human being with an eye towards recovery and nine key insights derived from the experiences of a wildland firefighter afflicted by this nervous system injury.

Sites drill seeded before the most recent fire had fewer, less frequent fires with longer fire return intervals (15–20 years) than aerially seeded sites (intervals of 5–8 years). The response of fire regime variables at unseeded sites fell between those of aerial and drill seeding. Increased moisture availability resulted in decreased fire frequency between 1994 and 2014 and the total number of fires since 1955 on sites with unseeded and aerially pre-fire seeding, but fire regimes did not change when drill seeded. Greater annual grass biomass likely contributed to frequent fires in the arid region. In Wyoming big sagebrush steppe, drill seeding treatments reduced wildfire risk relative to aerial seeded or unseeded sites.
As MTBS data have been used over the course of many years and for many disparate applications, users should be aware that the MTBS burned area and severity products have been actively reviewed and revised to benefit from more robust satellite image availability and to address any observed quality issues. In a sample of 123 remapped fires, we found no significant change in the burned area boundary products when compared to the original mapped fires; however, significant changes did exist in the distribution of unburned, low, and moderate burn severity pixels within the thematic product.
This webinar focuses on insects that have contributed to seed production problems in native plant production over the past two decades on the Colorado Plateau and in the Great Basin. The webinar was presented by Bob Hammon, Entomology/Agronomy Extension Agent, Tri River Extension Area.
