Tassie Greens out on a limb locking native forestry

The Tasmanian Greens have again got it wrong, calling for the locking up of native forest that is sustainably managed for multiple benefits, according to the Australian Forest Products Association. Source: Timberbiz The Mercury in Hobart reported that the Federal Government’s State and Territory Greenhouse Gas Inventories 2018 says Tasmania remained Australia’s only carbon-neutral state or ter...

Predicting stand age in managed forests using National Forest Inventory field data and airborne laser scanning

Abstract Background The aim of this study was to construct a nationwide stand age model by using National Forest Inventory (NFI) data and nationwide airborne laser scanning (ALS) data. In plantation forestry, age is usually known. While this is not the case in boreal managed forests, age is still seldom predicted in forest management...

Separating the impact of work environment and machine operation on harvester performance

Abstract In mechanized logging operations, interactions between the forest machines and their operators, forest resources and environmental conditions are multifold and not easily detected. However, increased computational resources and sensing capabilities of the forest machines together with extensive forest inventory data enable modeling of such relationships, leading eventual...

Mapping aboveground biomass and its prediction uncertainty using LiDAR and field data, accounting for tree-level allometric and LiDAR model errors

Abstract Background The increasing availability of remotely sensed data has recently challenged the traditional way of performing forest inventories, and induced an interest in model-based inference. Like traditional design-based inference, model-based inference allows for regional estimates of totals and means, but in addition for w...

Population and Stand-Level Inference in Forest Inventory with Penalized Splines

Penalized splines have potential to decrease estimates of variance in forest inventories with a design-based population-level inference, and a model-based domain-level inference by decreasing the likelihood of a model misspecification. We provide examples with second-order (B2) B-splines and radial basis (RB) functions as extensions to a linear working model (WM). Bias was not prominent, yet great...

Difference in regeneration conditions in Pinus ponderosa dominated forests in northern California, USA, over an 83 year period

<p>Forest inventories based on field surveys can provide quantitative measures of regeneration such as density and stocking proportion. Understanding regeneration dynamics is a key element that supports silvicultural decision-making processes in sustainable forest management. The objectives of this study were to: 1) describe historical regeneration in ponderosa pine dominated forests by spec...

Geocoding of trees from street addresses and street-level images

We introduce an approach for updating older tree inventories with geographic coordinates using street-level panorama images and a global optimization framework for tree instance matching. Geolocations of trees in inventories until the early 2000s where recorded using street addresses whereas newer inventories use GPS. Our method retrofits older inventories with geographic coordinates to allow conn...

Changes in land use, forest ownership, parcel size, and fragmentation in forests of the U.S

Using U.S. Department of Agriculture Forest Service Forest Inventory and Analysis (FIA) data, we examined changes in land use, ownership, parcel size, and parcel level in the U.S. South. Over a nominal 10-year period (2001 to 2011), 93.8 percent of the acreage did not change land use. Forest was the most common type and there was a small net gain of forested acreage. Of the forested acreage, 85.4 ...

Chapter 6 - A forest health retrospective: national and regional results from 20 years of Insect and Disease Survey data

The Forest Health Monitoring (FHM) national program of the U.S. Department of Agriculture Forest Service determines status, changes, and trends in indicators of forest condition across all forested lands (ch. 1). One of the central objectives of the FHM annual national reports is to present forest health indicator information from a national perspective, or from a multi-State regional perspective ...

An inventory of springsnails (Pyrgulopsis spp.) in and adjacent to the Spring Mountains, Nevada

Springsnails (genus Pyrgulopsis, hereafter pyrgs) are small freshwater aquatic gastropods that occur in isolated springs in western North America. Pyrgs are species of conservation concern, but patterns of occupancy and speciation are complex. We investigated patterns of occurrence for pyrgs in the Spring Mountains, Clark County, Nevada. We were primarily concerned with identifying springs contain...

Imputing forest inventory data to stands formed by image segmentation in Maryland's Green Ridge State Forest

Making stand based forest management decisions is difficult for landowners of large tracts because creating, managing, and updating stand maps is expensiv e and time consuming. Recently, advances in image processing in the area of image segmentation have made this task easier. The goal of the study reported here was to develop a method to delineate forest stands using image segmentation, assign to...

ABARES national study to identify characteristics of private forest wood

A national study is underway to identify the wood resource characteristics of private forest estates (private native forests and farm forests) and indigenous managed forests suitable for commercial uses. Source: Timberbiz Led by the Australian Bureau of Agriculture and Resource Economics and Sciences (ABARES), the study supports the National Forest Industries Plan – 2019-20 and 2020-21, Growing...
