Again an extremely dry year. We see in our monitoring it reduces bee numbers. We speculate this has something to do with floral resources. Just stumbled over this important paper that corroborates this: besjournals.onlinelibrary.wiley.com/doi/10.1111/...

Dryness, wetness and temporary flooding reduce floral resources of plant communities with adverse consequences for pollinator attraction

Changing precipitation patterns will adversely affect floral resources and pollinator attraction in agriculturally used temperate grassland, which might have widespread negative consequences for poll....

The winners take it all: het effect van intensief landgebruik op insecten

Nieuw onderzoek laat zien wat het steeds intensievere gebruik van grasland betekent voor insecten. Verrassend genoeg bleef bij intensiever gebruik het totale aantal insecten stabiel, maar de soortenrijkdom halveerde. Dit komt doordat soorten verschillend reageren. 85 procent van de soorten ging achteruit en de meeste verdwenen volledig, maar een paar wijdverspreide soorten profiteerden.

Politics is complicated Business is complicated Finance is complicated So why do they all expect ecologists to come up with simple actions & metrics for nature recovery Could they be spinning us a line?

Just because it is so beautiful. Megachile laechella. Rare in the Netherlands, but locally abundant in the dunes of Terschelling. The Dutch name 'zilveren fluitje' means silver whistle, after the high tone it makes while flying and the colour of.., well just look at it.

Excited to be presenting results from the SHOWCASE project and Agroforestry Group this month! Our farm trials across England have shown cover crops can increase earthworms by 65% in the following cash crops! AND agroforestry promotes worms too, especially in drought years 😎 Hope to see you there!🌾

... (reserve-equivalent) enhancement initiatives, supported by one-to-one advice, within or close to existing reserves." Here's an example of this working for waders in eastern England, spear-headed by the much-missed Mark Smart: wadertales.wordpress.com/2019/06/14/m... #ConservationScience🌍

Managing water for waders

Your task, should you choose to accept it, is to turn farmland into a haven for breeding waders. The only tools you have at your disposal are tractors and cows and we will give you permission to pu…

The geveltuin (“facade garden”) policy is found in most Dutch municipalities, as here in Delft. Provided they meet a set of requirements, including preserving footpath width, residents are encouraged to remove paving stones in front of their property and replace them with greenery. No permit needed.

Doing science biodiversity is great, but the impact is usually not very tangible. Together with citizen cooperative Land van Ons (@landvanons.bsky.social) we planted 300 meter of native hedgerow last December, and installed nest boxes. Today, I jumped of joy because the kestrel box is occupied!
