by

A. E. Campbell and R. H. M. Pratt2

INTRODUCTION

This bibliography provides a ready reference to technical

literature on establishing and maintaining shelterbelts . It includes

references on cultural practices , entomology , pathology , soils,

climatic conditions and tree species select ion.

References are listed by subject , using the Oxford Sys:em of

Decimal Classification for Forestry ,. and by author. Those pub.ica-

tions not available to the authors for review, but judg(�d to hdve a

direct bearing on the subject of shelterbelts , hc:ve been listed under
