Spotted owl home range and habitat use in the southern Oregon Coast Range.

We radiotracked 9 adult spotted owls (Strix occidentalis) in the southern Oregon Coast Ranges for 6-12 months. Owls selected home ranges that emphasized old growth within the landscape. Minimum convex polygon home ranges of 4 pairs were 1,153-3,945 ha and contained 726-1,062 ha of old growth. The percentages of. the home ranges in old growth were...

Georgia's forests, 2004

Between 1997 and 2004, the Forest Service, Forest Inventory and Analysis Program conducted the eighth inventory of Georgia forests. Forest land area remained stable at 24.8 million acres, and covered about two-thirds of the land area in Georgia. About 24.2 million acres of forest land was considered timberland and 92 percent of that was privately owned. Family forest...

Crown Condition

Photosynthetic capacity is dependent upon the size and condition of the tree crown. Trees with full, vigorous crowns are generally associated with more vigorous growth rates (Zarnoch and others 2004). Therefore, the Forest Service Forest Inventory and Analysis (FIA) Program measures a suite of crown condition indicators to evaluate forest health. Among the crown...

Latino outdoors: Using storytelling and social media to increase diversity on public lands

In 2013, for the first time in United States history, more than 50% of children younger than age one were minorities. Latinos are the nation?s largest-growing minority group, and by 2050 are estimated to comprise 28% of the total U.S. population. Despite the exponential growth of minorities generally and Latinos in particular, land-management agencies have been slow in...

Chapter 9: Crown Condition

Tree crown conditions are visually assessed by the U.S. Department of Agriculture Forest Service, Forest Inventory and Analysis (FIA) Program as an indicator of forest health. These assessments are useful because an individual tree?s photosynthetic capacity is dependent upon the size and condition of its crown. In general, trees with full, vigorous crowns are...

The North American Long-Term Soil Productivity Experiment: Coast-to-coast findings from the first decade

The National Forest Management Act of 1976 mandates that a site?s productive capacity must be protected on federally managed lands. Monitoring the effects of management on a site?s productive capacity is not easy, and in 1989 a national program of Long-Term Soil Productivity (LTSP) research was established to assist National Forests toward this end. The LTSP program...

Combining a generic process-based productivity model classification method to predict the presence and absence species in the Pacific Northwest, U.S.A

Although long-lived tree species experience considerable environmental variation over their life spans, their geographical distributions reflect sensitivity mainly to mean monthly climatic conditions.We introduce an approach that incorporates a physiologically based growth model to illustrate how a half-dozen tree species differ in their responses to monthly variation...

Mortality rates associated with crown health for eastern forest tree species

The condition of tree crowns is an important indicator of tree and forest health. Crown conditions have been evaluated during inventories of the US Forest Service Forest Inventory and Analysis (FIA) program since 1999. In this study, remeasured data from 55,013 trees on 2616 FIA plots in the eastern USA were used to assess the probability of survival among various tree...

Status of fusiform rust incidence in slash and loblolly pine plantations in the southeastern United States

Southern pine tree improvement programs have been in operation in the southeastern United States since the 1950s. Their goal has been to improve volume growth, tree form, disease resistance, and wood quality in southern pines, particularly slash pine (Pinus elliottii) and loblolly pine (P. taeda). The disease of focus has been...

Shape selection in Landsat time series: A tool for monitoring forest dynamics

We present a new methodology for fitting nonparametric shape-restricted regression splines to time series of Landsat imagery for the purpose of modeling, mapping, and monitoring annual forest disturbance dynamics over nearly three decades. For each pixel and spectral band or index of choice in temporal Landsat data, our method delivers a smoothed rendition of...

Virginia’s forests, 2016

Notable in this current resource bulletin is relative stability of forest land and timberland acreage and increasing maturity of the trees and stands that comprise it. Virginia?s total land area is 27.4 million acres, 16.1 million (58.7 percent) of which are forested according to the results of the latest forest inventory completed in 2016. This current estimate...

The roles of competition and habitat in the dynamics of populations and species distributions Ecology

The role of competition in structuring biotic communities at fine spatial scales is well known from detailed process-based studies. Our understanding of competition?s importance at broader scales is less resolved and mainly based on static species distribution maps. Here, we bridge this gap by examining the joint occupancy dynamics of an invading species (Barred Owl,...

Nursery stock quality as an indicator of bottomland hardwood forest restoration success in the Lower Mississippi River Alluvial Valley

Seedling morphological quality standards are lacking for bottomland hardwood restoration plantings in the Lower Mississippi River Alluvial Valley, USA, which may contribute toward variable restoration success. We measured initial seedling morphology (shoot height, root collar diameter, number of first order lateral roots, fresh mass, and root volume), second year field...
