A Scheme for Evaluating Feral Horse Management Strategies

Abstract EN

Context.

Feral horses are an increasing problem in many countries and are popular with the public, making management difficult.

Aims.

To develop a scheme useful in planning management strategies.

Methods.

A model is developed and applied to four different feral horse herds, three of which have been quite accurately counted over the years.

Key Results.

The selected model has been tested on a variety of data sets, with emphasis on the four sets of feral horse data.

An alternative, nonparametric model is used to check the selected parametric approach.

Conclusions.

A density-dependent response was observed in all 4 herds, even though only 8 observations were available in each case.

Consistency in the model fits suggests that small starting herds can be used to test various management techniques.

Implications.

Management methods can be tested on actual, confined populations.
