LPN was launched in 1948 under the leadership of Professor Carlos Manuel Beata Neves, to answer to the poet Sebastião da Gama appeal for the conservation of Arrábida Mountain.
In 1947, the poet sent his first alert and request for help to Eng. Miguel Neves, when the destruction of the forest began, to use the wood for a lime furnace. Upon learning of the situation, Prof. Carlos Manuel Baeta Neves, who was then teaching at the Instituto Superior de Agronomia (ISA), intervened and prevented the destruction of the forest.
One year later, LPN is founded, and Sebastião da Gama's letter was always referred to by its founder, Prof. Carlos Manuel Baeta Neves, as the origin of LPN:
"Mr. Engineer Miguel Neves.
Help! Help! Help! José Julio da Costa has begun (and is already well underway) the destruction of half of the Solitario Forest that belongs to him. I ask you to take care of it immediately. If necessary restore the death sentence. HELP!"
(Sebastião da Gama, 1947)
Since then LPN maintains a close contact with universities and science organizations, from Portugal and other countries. A substantial number of its members come from these institutions. They constitute a valuable technical Sponsors to validated intervention.
The building of LPN headquarters in Lisbon was donated in 1976 by the family Freire de Andrade and in 2000 suffered a substantial rehabilitation and it was converted in an Environmental Educational and Training Centre.
LPN owns and sustainable manages six estates in the Castro Verde region that are classified as biological nature reserves with a total area of 1800 hectares, where has an Environmental Educational Center.
LPN is accredited by National Institution for Quality Training (IQF), the Portuguese National Institute responsible to attribute this confirmation.
It should be noted that, throughout its history, LPN has contributed decisively to the creation of several Protected Areas, namely:
- National Park Peneda-Gerês (1971);
- Arrábida Natural Park (1976);
- Sado Estuary Natural Reserve (1980),
- Serra da Malcata Natural Reserve (1981);
- Southwest Alentejo and Vicentine Coast Natural Park (1988).
After the creation of the Protected Areas, LPN has always actively collaborated in their management and conservation by participating in Committees and Technical Boards.
Since the classification of the Municipality of Castro Verde as a UNESCO Biosphere Reserve on June 14, 2017, LPN is part of the Management Board, in partnership with the Municipality of Castro Verde and the Campo Branco Farmers Association, and is responsible for the governance of this Biosphere Reserve.
