The UK Habitat Classification System underpins Land App Baseline Habitat v2 and Land Management Plan v2 templates. In 2023 UKHab V2 was released and there were changes to the codes. The first wave of primary codes was completed in 2023, some minor adjustments to primary codes and the secondary codes in February 2024.
If you have plans created on these templates these have been migrated,
