When talking about land-use, it is, however, important to understand that land is not something that is used and then thrown away (ok, there are some heavily destructive uses, e.g. mining).

Land provides multiple services (biodiversity, carbon storage, water cycling, recreation, agricultural production, space for building stuff...). Some land-uses reduce the capacity of land to provide these services.
The next issue is the order in which the services are priorized. Some services have a more or less evident price tag (agricultural production, or space for buildings), while other (ecosystem) services, like water purification, carbon storage or biodiversity, are usually not taken into account by the market, except by really motivated people(TM) or administrations treating these services as public goods that deserve protection.

So, to make a fair comparison, it is important to assess the capacity of the different land-uses to provide the land-related services. And here it gets somewhat messy because management comes into play. E.g. 'agriculture' can be an conventional, pesticide-based soil degrading extractive system with all the consequences for soil, water and biodiversity; however, you can also have an agroforestry system that provides its functions in the interest of society and nature.

And here comes into play that e.g. pastures, despite taking up a lot of land, can be quite well-managed and score high on ecosystem services (of course, capitalism promotes the opposite: land degradation an unnecessary suffering*).
Just wanted to provide this context to the great map.

* of ccourse, reducing meat intake is a goal the whole society should work towards.

⛰️ It was time to get away from the desk and spend some time in nature together! On our team retreat, we went for a hike & lunch near Immenstadt in the Allgäu #Alps. It was amazing, to experience the #ecosystemservices that our group researches first hand: less stress & team spirit, and a stronger connection to #nature!

Who knew bat poo could be worth millions?
A new study shows Australia's grey-headed flying foxes are dropping bat ripple magic across millions of hectares. Their seed-dispersing guano helps grow a median of around 90 million new trees every year, mostly eucalypts.
That's an estimated 217 million to 955 million boost to the timber industry alone. Not bad for some flying forest gardeners who connect bushfire-scarred landscapes like pros.
Time to stop seeing them as pests and start celebrating these keystone heroes. Protect the bats, protect the forests.

Poo of 'endearing' bat worth hundreds of millions, study says

Bats are often thought of as smelly, ugly and noisy, but a study has revealed the economic and ecological value of one Australian species's poo.

I hope you enjoyed the #MarshMadness photographs which I have been posting this month, which have included photos of many of the wetlands I have had the rare privilege to study over my career. Wetlands are increasingly threatened globally, even here in Canada, and deserve our protection as a matter of urgency.

This highlights the importance of preserving these poorly-studied, ephemeral habitats, which are often the first to be lost as rivers become disconnected from their floodplains. When this happens, we lose not only the natural beauty of the riverscape, but also a larder for aerial insectivores - both birds and bats - which forage the river corridor

Early results from our study are showing that wetlands which fringe the main river channel, which may completely dry up by the end of the summer, nevertheless provide a much richer and more abundant source of food for insectivores when compared to more isolated wetlands, which are generally less productive.

Here in the Canadian Maritimes, rivers remain diverse and productive, hosting a rich insect fauna, which emerge around the time of arrival of migratory insectivores such as tree swallows. A close up of our light trapping system, shows both aquatic and terrestrial insects (including a very large hawk moth!).

In addition to quantifying insect biomass, we also collect specimens of flying insect species to analyze their fatty-acid content. Fatty acids are extremely important in the early development of swallow nestlings, and aquatic insects provide a rich source. Sampling is performed at dusk using UV light attractors, when insects are on the wing,.

The study, supported through an #NSERC Discovery Grant, is examining a set of five wetlands - four of which connect to the river, and another isolated (perched) basin. We measure flux of aquatic insects from these wetlands using pyramidal emergence traps, which collect emerging insects which provide a key food supply for aerial insectivores.

Aerial insectivore - both bats and birds - are declining globally. For this reason, knowing more about their critical breeding habitats is important to conserve these important species, many of whom migrate intercontinental distances from their overwintering areas to their summer breeding grounds here in Canada.
