More than 2,000 plant species have been recorded at Treborth Botanic Garden which has an area of 18ha (44 acres). Approximately half of these species are native to the British Isles and occur either naturally on the site or as introduced specimens. These include many rarities that are being maintained for conservation reasons, and in some cases for reintroduction into the wild. Half of the plant species at the Garden are non-native species from around the world that are used for scientific, educational and ornamental reasons. Many of these too, are of conservation value and, in some cases are being maintained as part of global efforts to protect a threatened or endangered species, e.g. the Wollemi Pine from Australia.
Vascular plants native (indigenous) to Treborth Botanic Garden
Treborth is a member of several global initiatives and international networks for plant conservation, and has active links with many other botanic gardens in the UK (e.g. the Royal Botanic Gardens, Kew and Edinburgh) and overseas, e.g. the Xishuangbanna Tropical Botanical Garden in China and the Katse Botanic Garden in Lesotho.
Treborth’s estate includes a rare, fringing shore example of ancient oak woodland that is protected by Site of Special Scientific Interest designation. This habitat is the recipient of a Welsh Government “Glastir” woodland management grant at Treborth.
As well as rare plants of conservation concern, many interesting and protected animal species are also found at the site including red squirrels. A small heronry exists on the Garden’s Menai Strait shoreline, and a record of night flying moths has been maintained for over 20 years.
Individual projects to conserve Welsh native species are being conducted at Treborth and much of the Garden’s teaching and outreach work focuses specifically on plant and animal conservation for a wide range of audiences.
