The hazel dormouse (Muscardinus avellanarius) is a rare and threatened species in many European countries. However, it is common and widespread in Lithuania where forest management practice, particularly small-scale clear-felling, is considered to be favourable for this species. The long-term study was carried out in regenerating clearing which fell in the area of the dormouse study site. The forest plot was clear-felled in the winter 2001/2002, and regrowth was thinned in 2004, 2007, 2010 and 2014. During 2003–2019, average adult dormouse density in regenerating clearing (1.6 ± 0.7 adults/ha) was significantly higher than average density in the entire area of the study site (1.0 ± 0.3 adults/ha). Clear-felling had only short-term negative effect on dormouse abundance. It increased already in the 3rd year after clear-felling when dormouse density exceeded 2 adults/ha and reached its maximum in the 7th–9th years after clear-felling. Dormouse abundance decreased since the 14th year after clear-felling. Thinning of regrowing woody vegetation had only temporary negative impact on dormouse abundance in the current or next year depending on the timing of thinning in early summer or autumn, respectively. Practice of small-scale clear-felling could be used for the hazel dormouse conservation in countries where this species is endangered.

榛树休眠（Muscardinus avellanarius）处于再生清除中：清除毛刺和再生长稀化对长期丰度动态的影响

榛树睡鼠（Muscardinus avellanarius）是许多欧洲国家的稀有物种和濒危物种。但是，这在立陶宛很普遍且普遍，那里的森林管理实践，特别是小规模的砍伐森林被认为对该物种有利。长期研究是在落入睡鼠研究场所的区域进行的再生清除中进行的。在2001/2002年冬季，森林地块被砍伐，2004、2007、2010和2014年间森林恢复稀疏。在2003-2019年间，在恢复砍伐中平均成年睡鼠密度（1.6±0.7个成年人/公顷）明显更高比研究地点整个区域的平均密度高（1.0±0.3个成年人/公顷）。砍伐对睡鼠的丰度只有短期的负面影响。休眠后第3年，当睡鼠密度超过2个成年人/公顷时，它已经增加，并在休眠后第7-9年达到最大值。清除后第14年以来，睡鼠的丰度下降了。生长的木本植物的稀疏在当前或明年仅对睡鼠的丰度产生暂时的负面影响，这分别取决于夏初或秋季稀疏的时间。在该物种濒临灭绝的国家，小规模砍伐的做法可用于榛睡鼠的保护。生长的木本植物的稀疏在当前或明年仅对睡鼠的丰度产生暂时的负面影响，这分别取决于夏初或秋季稀疏的时间。在该物种濒临灭绝的国家，小规模的透明砍伐活动可用于榛睡鼠的保护。生长的木本植物的稀疏在当前或明年仅对睡鼠的丰度产生暂时的负面影响，这分别取决于夏初或秋季稀疏的时间。在该物种濒临灭绝的国家，小规模的透明砍伐活动可用于榛睡鼠的保护。
