About us
Over 25 years caring for the land
We are a forestry and environmental engineering firm founded in Carcaixent in 2001. This is our story: a team that designs, builds and researches so that towns, forests and people can live together more safely and sustainably.
Our story
A small practice with a big idea: working for a more sustainable world
It all began in 2001 in Carcaixent, among orange groves and mountains. Back then we worked on Local Agenda 21 plans, helping town councils take their first steps towards sustainable development.
Over the years, that small practice grew into a multidisciplinary team of forestry engineers, environmental scientists, agronomists, biologists, emergency managers and land-use planners. And we learnt that designing good projects is not enough: you have to carry them out and be there when problems arise.
Today we have our own agroforestry crew, an AESA-certified drone unit and patents such as SIDEINFO, which protects villages and housing estates from wildfires. But we are still who we were at the start: people who care for rural areas and work from them.
