Ecological memory is the information and material legacies—the adaptations, individuals, and materials that persist after disturbance—that guide ecosystem response to disturbances. Resilience is directly related to ecological memory, and because resilience is desired in forest management, it is important to consider how ecological memory works. We propose that six spatial scales are needed to characterize ecological memory and its interactions with disturbance. These scales are: micro, tree, neighborhood, stand, meso and landscape. The nested hierarchy of microsites-tree-stand-landscape is well known, with widespread recognition of the need for diverse microsites, tree species and ages, and stand ages to create a managed landscape that harbors biodiversity. However, roles of the neighborhood and meso scales have been considered less often and have not been well integrated into overall legacy theory and its application to forest management. Here we show the key role of processes at these scales and their interactions with disturbance to maintain ecological memory, using cold-temperate and boreal forests from Minnesota, USA as a case study. ...

Effects of forest-fuel harvesting on the diversity of dead wood and epixylic macrolichens in clear-cuts Jäntti, Mari (2016)Energiapuuta käytetään yhä enemmän uusiutuvan energian lähteenä. Energiapuun korjuussa hakkuutähteitä eli kantoja, oksia ja latvuksia kerätään päätehakkuun ja harvennuksen yhteydessä hakkuualoilta. Tämä vähentää erityisesti ...
Halme, P.; Purhonen, J.; Marjakangas, E.-L.; Komonen, A.; Juutilainen, K.; Abrego, N. (Suomen metsätieteellinen seura, 2019)Dead wood profile of a forest is a useful tool for describing forest characteristics and assessing forest disturbance history. Nevertheless, there are few studies on dead wood profiles, including both coarse and fine dead ...
Contrasting Effects of Chronic Anthropogenic Disturbance on Activity and Species Richness of Insectivorous Bats in Neotropical Dry Forest Meramo, Katarina; Ovaskainen, Otso; Bernard, Enrico; Silva, Carina Rodrigues; Laine, Veronika N.; Lilley, Thomas M. (Frontiers Media SA, 2022)For prioritizing conservation actions, it is vital to understand how ecologically diverse species respond to environmental change caused by human activity. This is particularly necessary considering that chronic human ...
Interpreting wind damage risk : how multifunctional forest management impacts standing timber at risk of wind felling Potterf, Mária; Eyvindson, Kyle; Blattert, Clemens; Burgas, Daniel; Burner, Ryan; Stephan, Jörg G.; Mönkkönen, Mikko (Springer, 2022)Landscape multifunctionality, a widely accepted challenge for boreal forests, aims to simultaneously provide timber, non-timber ecosystem services, and shelter for biodiversity. However, multifunctionality requires the use ...
Fostering deadwood enrichment in managed forests – The importance of tree species and sun exposure for saproxylic species Vogel, Sebastian; Müller, Jörg; Thorn, Simon (Open Science Centre, University of Jyväskylä, 2018)Central European forests have been shaped by more than 2000 years of human exploitation. During this time, the increasing requirement of timber led to significant structural changes within the ecosystem. Because of declining ...
