Trends in windthrow management during the last 50 years in Lower Valais (essay) A review on the measures taken in forests hit by storms during the last 50 years reveals the mind-set behind the evolution of management operations. In the 1960s, to remove all dead wood in a stand was perfectly normal due to timber prices. Between 1984 and 1990, vast sums of money were pumped into the improvement of forest structures facing the threat of a general forest dieback. As a consequence, only few of the windthrow areas caused by storm Vivian remained with no intervention. Vivian also marked the beginning of manifold research activities and practical terrain examination in windthrow gaps. Conclusions of this first research phase resulted in a critical assessment of the windthrow areas caused by Lothar in 1999, considering different goals than systematic removal of damage wood and the prevention of bark beetle outbreaks. Since the 1990s, retaining timber after windthrow has been lively discussed, as well as the maintenance of the protection function against natural hazards and opportunities for biodiversity. Several handbooks were developed and successfully used for the planning and defining of top priority measures in damaged forests that resulted from disturbances in 2011 and 2012 in Lower Valais. These recent disturbances together with the certainty that storms will recur led to the formation of a task force in the canton Valais, aiming to organize both logistics and funds, as well as to define management priorities regarding a next hazard.

Responsibility for forest-linked dangers: examples from legal practice According to the Forest Policy 2020 of the Federal Council the share of old and dead wood should increase in Swiss forests. On the one hand, this is connected to positive ecological effects but on the other, to dangers, responsibilities and liability risks. Recent court and administrative decisions relating to accidents due to typical forest hazards such as falling trees and branches illustrate the legal situation for forest owners and enterprises as well as for forestry professionals. In the wooded environment near buildings and equipment there are obligations for the safety of traffic and passers-by. However, these obligations are limited by the reasonableness of protective measures and the personal responsibility of forest users. In this paper, the liability issue is illustrated by three legal case studies. The cases are assessed by the author, and the essential legal basis for liability is briefly summarized.

Ecological study of tropical semi-evergreen forest of Reiek in Mizoram was carried out to determine the stratification of the forest as well as to prepare life form spectrum of the plant communities. Mizoram is a part of Indo- Myanmar region which falls under one of the 35 biodiversity hotspots identified worldwide and therefore has a rich biodiversity. A detailed floristic survey was carried out. Plant species were collected, mounted in herbarium sheets and identified. Structural analysis was carried out and profile diagram was drawn. The forest was found to be composed of three layers in both the disturbed and undisturbed areas of the forest. The life form spectrum has been compared with Raunkiers normal spectrum to find out the phytoclimate of the region. The study area was found to have an abundance of phanerophytes indicating a phanerophytic climate

Jurasaidae are a family of neotenic elateroid beetles which was described recently from the Brazilian Atlantic Forest biodiversity hotspot based on three species in two genera. All life stages live in the soil, including the larviform females, and only adult males are able to fly. Here, we report the discovery of two new species, Jurasai miraculum sp. nov. and J. vanini sp. nov., and a new, morphologically remarkable population of J. digitusdei Rosa et al., 2020. Our discovery sheds further light on the diversity and biogeography of the group. Most species of Jurasaidae are known from the rainforest remnants of the Atlantic Forest, but here for the first time we report a jurasaid species from the relatively drier Atlantic Forest/Caatinga transitional zone. Considering our recent findings, minute body size and cryptic lifestyle of all jurasaids, together with potentially high numbers of yet undescribed species of this family from the Atlantic Forest and possibly also other surrounding ecoregions, we call for both field research in potentially suitable localities as well as for a detailed investigation of a massive amount of already collected but still unprocessed materials deposited in a number of Brazilian institutes, laboratories and collections.
