Habitat suitability for axis deer on the Hawaiian Island of Lanai

This dataset was developed to model habitat suitability for axis deer on the island of Lanai. Model parameters include: cloud cover at 1400 HST, ground surface slope, mean annual precipitation, NDVI, elevation, and bare soil. Datasets and indices derived for use in modeling efforts, as well as the suitability model developed for mouflon sheep, are included within this data release

Lanai habitat and ecological associations of two non-native ungulate species 2011

This series of five raster datasets includes three input rasters developed to model habitat suitability for two ungulate species on the island of Lanai; the two habitat suitability model raster datasets are also part of this data release. Input datasets were derived from WorldView-2 data to create vegetation (hereafter, NDVI) and bare ground indices, and from a Digital Elevation Model %

Normalized Difference Vegetation Index (NDVI) Data for the Hawaiian Island of Lanai, Derived from 2011 WV2 imagery

This dataset was developed to model habitat suitability for two ungulate species on the island of Lanai. This includes raster data derived from WorldView-2 data to create a normalized difference vegetation index (NDVI). This index, in addition to other datasets, was used to develop habitat suitability models for Axis deer and mouflon sheep. Datasets and indices derived for use in modeling

Slope Values for the Island of Lanai Derived from 2007 NOAA DEM Data

This dataset was developed to model habitat suitability for two ungulate species on the island of Lanai. Slope was derived from a 10-m resolution DEM raster dataset created by NOAA. This dataset, in addition to other datasets, was used to create the habitat suitability models. Datasets and indices derived for use in modeling efforts, as well as suitability models, are included within this

Hawaiian hoary bat roost departure-arrival metrics, Hawaii Island 2018-2019

Hawaiian hoary bats (Lasiurus cinereus semotus) were captured at multiple locations on the east side of Hawaii Island from May 2019 to October 2019. Radio transmitters were affixed to captured bats and, when possible, radio telemetry was used to locate bats in trees used for day-roosts. In 2019, three maternity roosts were identified however only two were suitable for video recording. T
