Burraga Swamp facts for kids
Burraga Swamp is a special natural area located in the Barrington Tops region of New South Wales, Australia. It sits next to Mount Lumeah and is surrounded by a cool, ancient rainforest. This rainforest is home to unique Antarctic beech trees and is found at a high altitude of 985 metres (about 3,230 feet) above sea level.

A Protected Natural Wonder
For many years, Burraga Swamp and the nearby forest were part of the Chichester State Forest. However, in the 1980s, the area became even more protected. It was added to the Barrington Tops National Park. This park is so important that it's now part of the World Heritage Gondwana Rainforests of Australia. This means it's recognized globally as a place of great natural value, protected for future generations.
Ancient Trees and Green Plants
The forest around Burraga Swamp is truly ancient. It features very tall Antarctic beech trees, some of which are an incredible 2,000 years old! These trees have seen a lot of history. You'll also find lots of soft mosses and beautiful ferns growing everywhere. Other types of trees that grow near the swamp include Golden Sassafras, Soft Corkwood, Prickly Ash, Possumwood, and Mountain Walnut.
How Burraga Swamp Was Formed
Burraga Swamp wasn't always a swamp. It was created a long time ago when a large landslide happened on the side of Mount Lumeah. This landslide blocked a natural basin, which then filled up with water, forming a lake. Over time, this lake slowly filled with natural materials like dead plants and soil. This process turned the lake into the swamp we see today. The swamp is now covered with different kinds of sedges (grass-like plants) and grasses.
Clues from Ancient Pollen
Scientists who study ancient plants, called palaeobotanists, find Burraga Swamp very interesting. They can learn a lot about the past by studying tiny bits of pollen found deep in the swamp's mud. These pollen records act like a history book, showing what plants grew here thousands of years ago and even giving clues about the climate.
What Pollen Tells Us
Pollen samples from the swamp show that Antarctic beech trees have only been common here for about 6,000 years. About 17,000 years ago, during the Last Glacial Maximum (a very cold period), the area was much colder and drier.
Around 13,000 years ago, Soft tree ferns became common. Then, about 11,500 years ago, Antarctic beech trees started to appear. They have only really taken over the area in the last few thousand years, when the weather became warmer and wetter. By studying pollen, scientists can understand the types of plants that have lived in this area for the past 40,000 years. During the coldest times, the plants were mostly dry, alpine types, similar to those found in high mountains today.
