摘要: Hair tubes were investigated as an indirect means of monitoring red and grey squirrel populations estimating densities. tube surveys live trapping was carried out in six sites, three conifer mixed conifer/broadleaf, four which had both squirrels resident. detected these but no with trapping. Reasons for this are discussed. These results suggest that hair effective method the spread different site types. Calibration between only data. The proportion visited by densities estimated from correlated (r = 0.846, d.f. =6, 0.034). generalised linear model, assessing relationship two methods, revealed a significant (P < 0.001); however, used explained very little variation within model (42%). use is unclear, further calibration data initial needed.
