context_section_description: The altitude ranges from 50–380 meters above sea level, and generally slopes southwards. 
  About 4% of municipal land in the eastern part of the region is protected territory. This includes the Kamchia Reservation encompassing 842 hectares along the banks of the Kamchia River. The reserve is listed as a biosphere reservation of UNESCO. All activities that may have a negative impact on the reservation: clear felling, industrial fishing, industrial gathering of herbs, mushrooms and flowers, the use of motorboats and the parking of vehicles near the river are limited in the zone. 
  The Kamchiiski Piasatsi protected area runs along the coast strip of the municipality. The area is one of the unique habitats of the black stork and over 20 other species of migratory and water birds.
