The value of leaving tree retention groups (TRGs) in clear-cuts has been verified in the last 30 years on the basis of the responses of various organisms, including carabid beetles. Most such research in Europe has been conducted in the Fennoscandian taiga. However, there is a lack of such studies of TRGs in the lowland temperate pine forests of Central Europe. Therefore I conducted a follow-up of carabid beetles in TRGs over the first three years after clear-cutting. The treatments were TRGs of different sizes, i.e. large (0.07 ha), medium (0.05 ha) and small (0.02 ha), together with the surrounding space in the clear-cuts and the neighboring control, i.e. mature unharvested pine stands. There were 3 sites, each with 6 TRGs (2 TRGs in each of the 3 size). (1) The rarefied species number, abundance and percentage of small zoophages in the assemblages inhabiting the control stands and TRGs were similar. (2) The proportion of forest fauna was higher in the assemblages inhabiting the control stands than in the TRGs, which was associated with colonization of TRGs by non-forest fauna and by the dominance it achieved. (3) Between the first and second year, the rarefied species number increased in the control stands and in the largest TRGs. (4) As the distance from the TRGs increased, the abundance and percentages of individuals representing small zoophages and forest species decreased, while the percentage of hemizoophages, generalists and open-habitat species increased. (5) In successive years there was a decrease in the proportion of forest fauna in the clearing and an increase in the rarefied species number, abundance, and proportion of individuals representing large zoophages and open-habitat species. (6) In the first two years of the study the carabid assemblages living in the control stands and those in the large TRGs were the most similar. (7) At the species level, Carabus violaceus was characteristic of large TRGs, and Amara consularis of small TRGs. Harpalus latus was a species characteristic of the area of the clearing furthest from the TRGs. In contrast with other research, I conclude that even such small TRGs as the ones I studied provide support for forest carabids in the first few years after clear-cutting. However, among the three sizes of TRGs, the largest ones (0.07 ha) offer the best protection for forest fauna. It is important to leave several such TRGs in the clear-cut area to form an archipelago of “habitat islands” facilitating the movement and survival of forest species.

在过去的30年中，根据各种生物（包括甲虫）的反应，已经证实了砍伐树木的保留小组（TRG）的价值。在欧洲，大多数此类研究都是在芬诺斯堪的亚的针叶林进行的。但是，在中欧的低地温带松树林中，缺乏有关TRGs的此类研究。因此，我在清除后的头三年对TRG中的甲虫进行了跟踪。处理方法为不同大小的TRG，即大（0.07公顷），中（0.05公顷）和小（0.02公顷），以及周围的空地和附近的对照组，即未收获的未成熟松木林。有3个站点，每个站点有6个TRG（3个大小中的每个都有2个TRG）。（1）稀有物种数 居住在对照林和TRG中的小噬菌体的丰度和百分数相似。（2）在控制林中的群落中，森林动物的比例高于TRG，这与非森林动物在TRG的殖民化及其取得的优势有关。（3）在第一年和第二年之间，对照林分和最大TRG中的稀有物种数量增加。（4）随着与TRG距离的增加，代表小型噬菌体和森林物种的个体的丰度和百分比下降，而半噬菌体，通才和开放栖息地物种的百分比增加。（5）连续几年，森林砍伐中森林动物的比例减少，稀有物种数量，丰度增加，和代表大型噬菌体和开放栖息地物种的个体比例。（6）在研究的前两年中，生活在控制站中的甲壳类动物与大型TRG中的甲壳类动物最为相似。（7）在物种层面，卡拉伯紫罗兰是大型TRG的特征，而Amara consularis是小型TRG的特征。Harpalus latus是距TRG最远的空旷区域的特征物种。与其他研究相反，我得出的结论是，即使是我研究过的小型TRG，在砍伐后的最初几年中也为森林锁扣提供了支持。但是，在三种TRG大小中，最大的TRG（0.07公顷）为森林动物提供了最好的保护。重要的是，将几个这样的TRG留在明确的区域，以形成“栖息地群岛”的群岛，从而促进森林物种的移动和生存。
