The large fire at the Siddick Pond Nature Reserve, near Dunmail Park on Maryport Road, spread along reed beds and gorse.
As a result, many birds were displaced during the sensitive nesting season.
However, there is now good news for the Friends of Siddick Pond as the reed beds have grown to around a foot high.
Chairman Bill Bacon says he thinks they will be fully re-generated by next spring.
"We're very pleased. It's coming on well, especially for wildlife. We hope by next year it will grow back to what it was like before."
Siddick Pond is owned and managed by Allerdale District Council with a little help from the Friends group.
