Eastern hemlock observations in the Linville River Gorge

This dataset has never been published

Sample of eastern hemlocks in the Linville River Gorge, NC, USA. FieldNumbers 1 to 41 indicate sampling plots with 4 m radius. One to six hemlocks were observed and measured within the plots. FieldNumbers TCS1 to TCS13 indicate locations of individual large eastern hemlocks.

Title Mapping and monitoring of HWA induced hemlock mortality in Southern Appalachian landscapes
Funding This study was made possible by financial aid from Finnish Graduate School in Forest Sciences (GSForest), Finnish Academy project “Centre of Excellence in Laser Scanning Research” (CoE-LaSR, decision number 272195), and by the US Forest Service through USDA Forest Service cooperative agreement SRS-12-CA-11330129-077.
Study Area Description The study area is located in the Lower Linville River watershed of the Grandfather Ranger district (GF) (35˚56’N, 81˚55‘W), Pisgah National Forest, Southern Appalachian Mountains, western North Carolina, USA. The Linville Gorge wilderness area covers most of the study area. The majority of the wilderness area has remained unlogged and it is one of the largest old-growth forests in the region. However, the area has been subjected to frequent forest fires. Elevations range from approximately 350 m above sea level (a.s.l.) at the southern part of the watershed and the bottom of the river basin to 1300 m a.s.l. on the upper ridges. The topography is very rugged with prominent cliff-like bluffs dividing upper and lower slopes.

Sampling Methods

FieldNumbers 1 to 41 indicate sampling plots with 4 m radius. One to six hemlocks were observed and measured within the plots. Individual hemlocks were located with a distance and an azimuth to the plot center. FieldNumbers TCS1 to TCS13 indicate locations of individual large eastern hemlocks. Diameter-at-breast-height, height, and defoliation level of all hemlocks were inventoried.

Study Extent Hemlocks were located at 39 randomly chosen and accessible location at the Linville River Gorge. Most of the plots were established uphill, west of the Linville River

Method step description:

  1. Diameters-at-breast-heights were measured with talmeter, height with hypsometer, and defoliation intensity was assessed visually at 10% prescision.
