An arboretum is a specialized botanical collection consisting entirely of trees and shrubs.

Unlike a standard park, an arboretum acts as a living museum of woody plants. These collections are managed by organizations dedicated to stewardship, which means they actively care for and protect the plants. While many arboreta began as small sections within larger gardens or parks to display non-local species, many modern versions are part of larger botanical gardens. These contemporary sites serve a dual purpose: they are beautiful public spaces and vital centers for scientific study.

To manage these living collections, experts use specific organizational methods. Individual trees are often labeled with identification tags so that visitors and scientists can recognize each species. Some collections are organized systematically to assist with scientific research or to optimize plant growth. Specialist collections also exist for specific plant groups. For example, a pinetum is an arboretum that focuses on conifers. Other specialized types include a saliceta for willows, a populeta for poplars, and a querceta for oaks.

Other related collections might include a fruticetum, which is a shrubbery, or a viticetum, which focuses on vines. For tender trees that require warmth, a large greenhouse called a palm house may be used.

The history of moving and collecting trees stretches back to ancient times. Egyptian pharaohs practiced early arboriculture by importing exotic woods, such as ebony from the Sudan and cedar from Syria. One of the first recorded attempts at transplanting foreign trees involved the Pharaoh Hatshepsut. She sent an expedition to Punt and returned with thirty-one live frankincense trees. To keep them alive during the voyage, the roots were carefully preserved in baskets. These trees were eventually planted in the courts of her mortuary temple complex at Deir el Bahri.

In the late 13th century, Kublai Khan demonstrated a grand scale of tree collection. According to Marco Polo, the Khan collected various evergreen specimens from across the Mongol Empire. These trees were transported by elephant to his winter capital, Khanbaliq. He planted them on a massive artificial structure called the "Green Mound." This mound was one hundred paces high and over a mile in circumference.

The ground of this mound was even covered in pieces of green stone. Much earlier, the Trsteno Arboretum in Croatia was already established by 1492. The Gučetić family created this garden, which included a span aqueduct built to irrigate the site. This aqueduct remains in use today.

The modern concept of the arboretum was shaped significantly in the 19th century. John Claudius Loudon, a prolific landscape gardener and writer, is credited with the first English use of the word "arboretum" in 1833. His 1838 work, *Arboretum et Fruticetum Britannicum*, remains one of the most significant texts on the subject in British history. This eight-volume set provided an account of all trees and shrubs hardy in the British climate. It also included an international history of arboriculture and the economic value of trees.

Loudon advocated for the creation of national arboreta and systematic collections in public parks and private estates. He viewed the Derby Arboretum, opened in 1840, as a vital demonstration of the benefits of public tree collections.

Today, arboreta serve as critical sites for conservation and biodiversity. The Udhagamandalam Arboretum in India was established in 1992 to conserve native and indigenous trees. Before its creation, the area was a neglected micro watershed where urban waste contaminated the water supply. In New Zealand, the Eastwoodhill Arboretum holds approximately 4,000 different trees, shrubs, and climbers. It represents one of the largest collections of Northern Hemisphere trees located in the Southern Hemisphere.

Another notable site, the Taitua Arboretum in New Zealand, covers twenty-two hectares and hosts 1,500 species of trees, attracting about 60,000 visitors annually.

Large-scale projects continue to expand our understanding of forest ecosystems. The National Arboretum Canberra in Australia is a massive 250-hectare development. It contains a significant stand of 5,000 Himalayan Cedars and a large Cork Oak plantation. The site is home to the world's largest planting of the Wollemi pine and aims to eventually host 100 different forests and 100 gardens.

Similarly, the RJ Hamer Arboretum in Australia was the first known instance where a forest-style arboretum was established entirely through planting. These diverse collections connect various scientific fields, from ecology to urban planning, ensuring that woody plants are preserved for future generations.
