Lockyer Observatory

Many of us have stood in a special place on a clear night, looking up at the vast expanse of the cosmos. But while the telescopes at the historic Norman Lockyer Observatory are pointed towards distant galaxies, what vibrant natural world is thriving right here on the ground?

Perched on Salcombe Hill, east of Sidmouth, the Norman Lockyer Observatory (NLO) is a landmark of scientific heritage. It was established in 1912 by Sir Joseph Norman Lockyer, a pioneering astronomer renowned for founding the scientific journal Nature and for his discovery of the element helium in the Sun's spectrum. Today, the observatory continues its mission as a historic and active center for amateur astronomy, meteorology, and science education. This unique site represents a powerful blend of pioneering scientific history and ongoing astronomical discovery.

The extensive grounds of the observatory have undergone a significant transformation. The land was originally heathland, but for many years it was landscaped with manicured lawns to provide easy access to the telescopes and maintain a "tidy" appearance. In recent years, however, a conscious effort has been made to restore the original habitat. Areas of gorse scrub have been cleared to encourage the natural return of heathers. This important conservation work is powered by dedicated volunteers like Heather Spratt, who has been diligently controlling bracken in the observatory grounds for 17 years. This shift from a tamed landscape to a wilder one is a crucial step in supporting and enhancing local biodiversity, reflecting a broader, sometimes contentious, community-wide conversation about whether such natural spaces are vital wildlife corridors or simply signs of untidiness.

The Norman Lockyer Observatory (NLO), perched on Salcombe Hill, is currently undergoing a significant transition in both its ownership and its ecological management as of early 2026.

Habitat Recovery: Restoring the Lowland Heath

While the society is famous for its telescopes, the 47-acre site is also home to one of the last remaining remnants of Coastal Lowland Heath in East Devon. Habitat recovery is a core objective of their management plan.

• Rhododendron Eradication: The primary ecological activity involves the systematic removal of invasive Rhododendron ponticum. This species had previously smothered the native heathland, preventing the growth of heather and gorse.

• Heathland Demonstration Site: The observatory grounds are now managed as a demonstration conservation site. The goal is to revert the scrubland back to a traditional heathland mosaic, which is a priority habitat under the Devon Nature Recovery Plan.

• Directing the Recovery: The recovery work is directed by the NLOS Estates Team in collaboration with local conservationists. They often work alongside the Sid Valley Biodiversity Group (SVBG) and the National Trust (who manage the adjacent land on Salcombe Hill) to ensure the site acts as a continuous wildlife corridor.

• Citizen Science & Dark Skies: Habitat recovery at the NLO is uniquely linked to "Dark Sky" preservation. By maintaining a natural, unlit buffer of heathland, the directors ensure that the local ecosystem supports nocturnal species like Nightjars and Bats, which are sensitive to light pollution.

A Flutter of Wings in the Gorse

The restoration efforts at the observatory aim to extend the success of vital local habitats like the adjacent Soldiers Hill, a meadow renowned as a haven for numerous butterfly species. The area is a haven for varieties such as the Meadow Brown, Common Blue, Small Copper, Gate Keeper, Marbled White, and Large Skipper. These insects are energized by the nectar-rich plants that thrive here, including knapweed, brambles, and thistles. The vibrant flutter of their wings serves as a living testament to the success of the habitat restoration efforts, showcasing a thriving ecosystem reborn from manicured lawns.

Creatures of the Night (and Day)

The biodiversity of the area extends beyond insects. The presence of nocturnal hunters in the wider landscape is significant, with ecological surveys in the Sidmouth area being conducted for species such as pipistrelle and myotis bats. By day, visitors may be treated to the sight of buzzards soaring magnificently over the Salcombe Regis area as they scan the landscape for prey. The presence of these predators, both night and day, indicates a healthy and interconnected habitat, of which the observatory grounds are a vital part.

The Norman Lockyer Observatory stands as a rare and remarkable place where two worlds of exploration meet. It is a site dedicated to gazing outward at the infinite wonders of the cosmos, while simultaneously nurturing and conserving the precious natural world on Earth. It leaves one to wonder: does looking after our own small corner of the world better equip us to understand the vast universe beyond it?
