Because the beaver isn't just an animal; it's an ecosystem!

Tag: Nitrates and biodiversity


Fair warning. There are two fairly predictable puns in this mornings post. Never mind. It’s worth it.

Here’s a nice interview about the research done on the effects of the beavers in Devon by the Dr. Brazier at the University of Exeter. The interview is accompanied by some beautiful photos from the Wildwood Trust. Enjoy!

I spent most of yesterday working on my mural presentation for PRMCC. I made this to show something about the history of the beaver story being important to Martinez. I’m thinking of calling it “A community tale” or maybe “A community tail“…

tail

Seems like it makes the point to me. What do you think?

BK sent this my way this morning and it’s pretty alarming. Apparently nitrates are in our lovely high mountain lakes too and affection biodiversity everywhere. Gosh I wish we only knew of SOME ANIMAL that was good at removing nitrates cheaply…but I’m just drawing a blank…any thoughts?

‘Frightening’ findings foretell ills for ecosystems

 The study’s lead author, recent PhD graduate Beth Hundey (Geography), showed, for the first time, that 70 per cent of nitrates in high mountain lakes in Utah are from human-caused sources – with fertilizers having, by far, the most impact at 60 per cent, along with another 10 per cent caused by fossil fuels. The research suggests these findings could apply to other mountain ranges in western North America.
Unlike temperature and dissolved oxygen, the presence of normal levels of nitrates usually does not have a direct effect on ecosystems. However, excess levels of nitrates in water can create conditions that significantly alter an area’s biodiversity
Wow. That’s terrible. The very thing which feeds us is also killing us – in more ways than one. If only there was a simple, cheap, effective solution. You know something really hardy that every state could afford and was guaranteed to make a difference…
