The Parco degli Aironi, or Heron Park, is a rare example in the Lombardy Region of the successful conversion of a former quarry, made possible by resolution No. 240 passed by the Province of Varese, along with the regeneration of the whole area facing the San Giacomo Fountain. Then it was recognised as possessing the right environmental credentials to be awarded the status of Local Park of Interest and has thus become part of the Regional Ecological Network.
The Heron Park comprises 45 hectares of green area with about 14,500 planted tree species. Depending on how these are distributed you can find various areas.
Inside the animal pens there is a small wood consisting almost exclusively consists of robinia, or black locust, trees.
The herbaceous layer is essentially made up of grasses of different types.
This area from spring to autumn is a rich feast of wild species of flora. The tree species that surround it come from past plantings or spontaneous additions, as in the case of the black locust trees. Here you can find ash, alder, alnus, birch and poplar trees. Of particular interest are the reeds and rushes, located near the waterway leading to the lake.
It is a hydric shrubbery around the birdwatching area. An area of the park, until recently dominated by the almost exclusive presence of Buddleja davidii, or Black Knight/butterfly bush, a vigorous alien species and weed. In the park many species of mushrooms can also be found.
The park is home to numerous species of avifauna, typical of humid environments in Lombardy, along with various floating fauna that find shelter and refreshment here.
These are fenced areas set aside to allow animals difficult to observe in nature such as deer, fallow deer and mouflon (wild sheep) to graze. An unrepeatable chance to get to know these animals close up, to learn about plant species typical of our area and pick them out from those that have come from afar, thanks to the hand of Man.
