Depends what you mean by wildlife, lol?
If you mean wild animals ... then I suppose it is very different here to Chile.
And the wildlife by the Lake very different to wildlife up here in the Jura moutons where I live. In the area we have so much wildlife, with many birds of prey, kestrels, buzzards, red kites and black kites, and peregine falcons. Song birds would need pages to list, but one of the rarities to be seen at the Creux-duVan, if the wall creeper, latin Tichodroma muraria, a lovey grey and bright pink bird. For mammals, depending on size and area, red/brown squirrels, pine and beech martens, badgers, foxes, beavers in some places, marmots, lynx and even the odd and elusive wolf. And so much more ... The flowers of the Jura are amazing and so varied too. For great walks I recommend the Gorges de l'Areuse (from Boudry), the Gorges de la Poetta Raisse (from Motiers, accessible by train from Neuch), the Ferme Robert and le Creux du Van (both accessible from Noiraigue station where you can hire an electric bike) - where you can see Ibex (big horned sheep like) providing you are there before 10.30 or after 4pm. Walk to the top of the hill to the panorama, to see the whole of Romandie and with a panorama of the Alps, including Mt Blanc. There are 30+ types of bats in the area. Go to La Morille information Centre at Champ du Moulin, half way up the Gorges de l'Areuse. There is also an info centre at the Ferme Robert below the Creux-du-Van. Area is also very rich in amphibians, frogs, newts, grass snakes, adders, etc.
Pro-natura regularly organises walks with experts. Coming soon: marmots at the Chasseron, on Sat 17th August, Chasseral geology, flora and fauna on 14th September, And Gorges de La Jogne from Brock to Charmey (Fribourg area) on 5th October. And so many more, including residential courses, etc.

There is a lovely wildlife magazine that covers Suisse Romande mainly, but also other parts and FRance, based in Neuchatel called 'La Salamandre'. A wonderful publication with amazing photos and drawings and specialist features. Go to their office in Neuchatel, they will make you very welcome.
If you tell me which field you are particularly interested in, I may be able to point you in the right direction, and take you to the right place. I am a linguist, but my wildlife speciality is badgers, if that can be of any use.
