The history of Mangalavanam Bird Sanctuary is intertwined with the development and conservation efforts of the region. Here's an overview of its history:

(1) Early Utilization as Timber Depot:

The region that now houses the Mangalavanam Bird Sanctuary had a different role in its past. It was formerly utilized as a timber depot, known as the Ernakulam Timber Depot. This depot played a crucial role in the storage and distribution of timber, primarily facilitated by ferry boats. This phase marked a time when the wetland's ecological significance was not fully recognized, and human activities centered around timber management.

(i) Malayattoor Division (Pre-1970 to 1970): Until 1970, the timber depot fell under the administration of the Malayattoor division. This division oversaw the operations and management of the depot, albeit without a focus on the environmental implications of the site.

(ii) Timber Sales Division, Kalady (1970 to 1981): Subsequently, from 1970 to 1981, the management of the depot shifted to the Timber Sales Division located in Kalady. This period continued the trend of utilizing the area for timber-related activities.

(iii) Social Forestry Division, Ernakulam (1981 Onwards): A significant shift occurred in 1981 when the Social Forestry Division, Ernakulam took control of the area. This change in administrative jurisdiction marked the beginning of a transition from resource exploitation to ecological preservation.

Recognizing the ecological importance of Mangalavanam, local environmentalists, bird enthusiasts, and conservationists began advocating for the protection and preservation of the wetland. Their efforts highlighted the need to maintain a balance between urban development and conservation.
