In the woodland steppe of the Turgen-Kharkhiraa and Chan Chochin mountains of northwest Mongolia, detailed studies of stand and vegetation structure, growth dynamics, and soils of the local larch woodland have been carried out during the 1995 - 1997 period. On the basis of these studies, it has been possible to carry out a structural and plant soci...

DEUTSCH In den Medien werden Blühflächen und Blühstreifen als schöne, schnelle und einfache Lösung gegen das Insektensterben gepriesen. In der Landwirtschaft werden sie im Rahmen der EU-Förderprogramme, vor allem in der 2. Säule, gefördert. Neben den landwirtschaftlichen Flächen sind aber auch in Gärten und Kommunen zuletzt viele Blühflächen entsta...

Between 2010 and 2015 several management projects funded by the Saxon state guideline “Richtlinie Naturliches Erbe” were carried out to save the only population of Gentianella lutescens in Germany in the “Osterzgebirge” (Eastern Ore Mountains) near the town of Altenberg (Saxonia). Ex-situ conservation cultures were established in the botanical gard...

The paper presents a brief outline of the nature conservation history in Mongolia and sets forth the present stand following the political turnaround of 1991. The laws important for nature conservation will be dealt with and their inadequacies highlighted through several examples. The problems lie above all in an insufficient flow of information an...

Im Herbst 1995 wurden Untersuchungen zu Vegetation und Bodenverhältnissen sowie zu Physiognomie, Altersstruktur und Dynamik in Lärchenwäldern des Charchiraa-Gebirges im Nordwesten der Mongolei durchgeführt. Dabei konnte eine Pflanzengesellschaft ausgegliedert werden, die nach der dominanten Pflanzenart „Bärentrauben-Lärchenwald” genannt wird. Sie w...

In the autumn of 1995, studies were made in vegetation and soil conditions as well as in physiognomy, age structure and dynamics in the larch forests of the Charchiraa Mountains in the northwest of Mongolia. By that, a plant community could be distinguished which is named 'Arctous alpina-larch forest'. It is interpreted as a subassoziation of the B...

Questions

Question (1)
Question
There are many tipps and tricks and stretegies how to protect wild insects during mowing. It's clear: every mowing kills many insects. One is clear and quasi-standard in nature conservation resp. extensive farming on grassland: mowing later in the year (e.g. june) and mowing only once or two times a year.
More difficult is the question about the time of day to save as many insects as possible.
The mostly published tip is to mow in the morning when it's still cold and moist. The reason mostly mentioned for this strategy is: in the morning, no insects are flying in/over the meadows so the mortality risk is significant lowered. You can read this tip quite often, in nature conservation papers as well as in agricultural papers and media.
I assume this tip to be more or less completely nonsens. Only honey bees and probably some bumble bees are still in their hive or nest in the early morning. The vast majority of the grassland insects is staying inside the vegetation, both during the night, and during cool and moist wheather conditions. I guess this tip results from the observation that no (honey) bees are flying in the early morning.
To save as many insects as possible during mowing, I believe (like many other experirenced colleagues do) that mowing at noon or in the afternoon during hot and sunny wheather conditions can save many more flying insects (esp. pollinators) because:
1) they are flying instead of sitting inside the vegetation
2) they are more mobile overall
3) they react faster
4) they can escape/fly away better and faster
My suggestion is to spread this tip as far as possible inside both the nature conservation community, and the agricultural community and to explain whenever it's possible why the old tip is rather harmful than helpful in terms of insect conservation.
What do you think? Do publications exist about this topic?

Project
With the „NATÜRLICH BAYERN” initiative, a key action of the new „Blühpakt Bayern“, the Bavarian Landcare Associations (Landschaftspflegeverbände) will improve areas of the public sector, agriculture and industry into species-rich habitats for insects over the next five years. Here, stakeholders will be advised on insect-friendly land management. The German Association for Landcare (DVL) coordinates and accompanies the project with a nationwide media campaign. The Bavarian State Ministry of the Environment and Consumer Protection funds the project.
Project
Setting up an upgrade training course called "Natura 2000-Manager" at FH Erfurt for master students as well as for external participants who work in nature conservation or landscape planning. The training course will intensively use multimedia devices such as high-resolution 360 ° panoramas and 3D VR headsets. The goal is to teach the participants all needed scientific, ecological, legal, and engineering issues about the Natura 2000 sytem of the EU, it's species and it's habitats.
