The trust held its first formal meeting, headed by the Dean of Jersey, Samuel Falle, on 3 August 1936, and was incorporated in the following year by the States of Jersey. The trust is now the island's largest private land owner, caring for over 130 sites.
The trust owns several farms which are of historic interest, some of these are described below.
The Elms is a former 18th-century farm, in St. Peter's Valley, which has been the trust's headquarters since 1978.
It is not operated as a museum, but some areas are normally open to visitors.
The earliest records indicate that a building was located here in 1445.
The museum is open to the public, from June to September. In October, it becomes the venue for La Faîs'sie d'Cidre (a cider making festival).
This working farm is located in St. Lawrence. Some structures here were built in 1666.
Le Moulin de Quétivel, a restored watermill which is open to the public and grinds flour for sale in its shop.
The trust owns a number of former military buildings in Jersey. Some of these are listed here.
Câtel Fort is an 18th-century guardhouse, situated overlooking Grève de Lecq Bay.
In 1810, construction of Grève de Lecq Barracks was started, and a garrison was stationed here until the 1920s. It was able to house up to 250 troops.
The barrack buildings, located in St Mary, have been restored and are open to the public from May to September.
The building has had further additions made, probably during the 18th century.
In 2012, a 99-year lease on the property was made available to purchase from the trust.
In 2012, plans were submitted to improve facilities at the wetland area known as St. Ouen's Pond, in St. Ouen. The plans include a substantial upgrade of the existing bird hide. The costs are estimated to be £102,000, and funded by the Tourism Development Fund (States of Jersey) and the RBC Blue Water Project (Royal Bank of Canada).
Le Noir Pré comprises two adjacent wet meadows, also known as the orchid fields because the Orchis laxiflora can be found growing here. The Channel Islands are the only place in the British Isles where this orchid can be seen, normally during May and June.
The site is used as a venue for the trust's annual Sunset Concert.
La Vallée des Vaux is a woodland valley which lies in the north of St Helier, parts of which are owned by the trust.
Le Don Journeaux, a house in St. Clement.
