在西萨福克郡的一个可耕地上，通过活体诱捕和检查被杀动物的胃内容物，研究了木鼠的生态学。研究区域包括几块田地，但只有很短的树篱长度，并且远离其他树篱和树林。我们全年都把木鼠困在开阔的田野里，并在那里发现了它们的洞穴。种群密度与落叶林地报告的种群密度相当，种群的季节性变化、范围行为和繁殖季节的时间也大致相似。幼鼠的存活率在繁殖季节内和繁殖季节之间变化很大，当幼鼠取代成年繁殖种群中的越冬动物时，存活率趋于提高。在冬季，当主要食物为谷物、废甜菜根、杂草种子和土壤无脊椎动物时，木鼠对不同作物的田地没有明显的偏好。在春天和初夏，它们更喜欢冬麦地，因为那里播种的杂草提供了它们大部分的食物。
The ecology of Wood mice (Apodemus sylvaticus) was studied by live trapping and by examining the stomach contents of killed animals on an arable farm in West Suffolk. The study area included several fields but only a short length of hedgerow and was distant from other hedges and woods. Wood mice were trapped in the open fields throughout the year and their burrows were also found there. Population densities were comparable with those reported from deciduous woodland and seasonal population changes, ranging behaviour and timing of the breeding season were also broadly similar. The survival rate of juvenile mice varied greatly within and between breeding seasons tending to improve when young of the year replaced overwintered animals in the adult breeding population. Wood mice showed no marked preference for fields with different crops in winter when the main foods were grain, waste sugar beet roots, weed seeds and soil invertebrates. In spring and early summer they preferred winter wheat fields where seeding weeds provided most of their food.
