Estimating aboveground carbon density across forest landscapes of Hawaii: Combining FIA plot-derived estimates and airborne LiDAR

Remote sensing data have increasingly been employed in combination with field plot data to estimate aboveground carbon (C) stocks across heterogeneous forested landscapes around the world. The Forest Inventory and Analysis (FIA) program of the US Forest Service offers a gridded network of field plots which potentially can be linked to airborne Light Detection...

Estimating sawmill processing capacity for Tongass timber: 2005 and 2006 update

In spring 2006 and 2007, sawmill capacity and wood utilization information was collected for selected mills in southeast Alaska. The collected information is required to prepare information for compliance with Section 705(a) of the Tongass Timber Reform Act. The total estimated design capacity in the region (active and inactive mills) was 289,850 thousand board feet (...

A state-space modeling approach to estimating canopy conductance and associated uncertainties from sap flux density data

Uncertainties in ecophysiological responses to environment, such as the impact of atmospheric and soil moisture conditions on plant water regulation, limit our ability to estimate key inputs for ecosystem models. Advanced statistical frameworks provide coherent methodologies for relating observed data, such as stem sap flux density, to unobserved processes, such as...

Timber harvests in Alaska: 1910-2006

This publication provides estimates of total softwood harvest, by owner, for Alaska for 1910-2006. This information is a mix of reported and estimated data. These data are being used to develop assumptions needed in forest planning by both public and private forest managers.

Alaska's lumber-drying industry—impacts from a federal grant program.

A survey determined that installed dry kiln capacity in Alaska more than doubled to an estimated 220 thousand board feet (mbf) within 4 years (2000-2004). This increased ability to produce dry lumber and value-added products resulted from industry efforts to obtain federal funding to support a dry kiln grant program. This report reviews grantees' progress in...

Developing estimates of potential demand for renewable wood energy products in Alaska

Goal three of the current U.S. Department of Agriculture, Forest Service strategy for improving the use of woody biomass is to help develop and expand markets for woody biomass products. This report is concerned with the existing volumes of renewable wood energy products (RWEP) that are currently used in Alaska and the potential demand for RWEP for residential and...

Ecophysiological variation of transpiration of pine forests: synthesis of new and published results

Canopy transpiration (E_C) is a large fraction of evapotranspiration, integrating physical and biological processes within the energy, water, and carbon cycles of forests. Quantifying E_C is of both scientific and practical importance, providing information relevant to...

Baseliner: an open source, interactive tool for processing sap flux data from thermal dissipation probes.

Estimating transpiration from woody plants using thermal dissipation sap flux sensors requires careful data processing. Currently, researchers accomplish this using spreadsheets, or by personally writing scripts for statistical software programs (e.g., R, SAS). We developed the Baseliner software to help establish a standardized protocol for processing sap...

Sensitivity of stand transpiration to wind velocity in a mixed broadleaved deciduous forest

Wind velocity (U) within and above forest canopies can alter the coupling between the vapor-saturated sub-stomatal airspace and the drier atmosphere aloft, thereby influencing transpiration rates. In practice, however, the actual increase in transpiration with increasing U depends on the aerodynamic resistance (RA) to vapor transfer compared to canopy resistance to...

Cold air drainage flows subsidize montane valley ecosystem productivity

In mountainous areas, cold air drainage from high to low elevations has pronounced effects on local temperature, which is a critical driver of many ecosystem processes, including carbon uptake and storage. Here, we leverage new approaches for interpreting ecosystem carbon flux observations in complex terrain to quantify the links between macro-climate...

Laurel Wilt: a new and devastating disease of redbay caused by a fungal symbiont of the exotic redbay Ambrosia beetle

The mysterious death of redbay Persea borbonia (L.) Spreng.) trees on Hilton Head Island, South Carolina, and surrounding areas was first reported in local newspapers in 2003. Thousands of redbays were dying in the low country of South Carolina, and by the end of 2004 officials on Hilton Head were estimating that they had lost 75-80% of the island...

The forest hydrologic cycle is expected to have important feedback responses to climate change, impacting processes ranging from local water supply and primary productivity to global water and energy cycles. Here, we analyzed water budgets of pine forests worldwide. We first estimated local water balance of forests dominated by two wide-ranging species: Pinus...
