Massachusetts has nearly 1300 coldwater streams that support wild Brook Trout. While the majority of these streams are in the less developed western part of the state there are several dozen that still remain within the more densely-populated suburban landscapes of eastern Massachusetts. Unfortunately, the coldwater habitat in these streams is disappearing through the combined effects of increasing development, groundwater extraction, and climate change. Two streams can be used as pertinent examples outlining wild trout conservation efforts in this region of the state. Through wide-ranging collaborative efforts, Traphole Brook and Sucker Brook have both undergone work to restore connectivity and coldwater habitat with the goal of conserving wild Brook Trout populations. Dam removal and habitat restoration has allowed Brook Trout in Traphole Brook to expand their range to occupy previously uninhabitable reaches. Conversely, similar efforts at Sucker Brook have not had the same impact and Brook Trout there have recently become extirpated. To better understand why restoration has not had the desired impact, Brook Trout from nearby streams have been reintroduced into the remaining isolated coldwater habitats in Sucker Brook. Each were implanted with a PIT tag to monitor movements past fixed antenna locations at 1) a recent dam removal, and 2) a recent culvert upgrade. Early results indicate that reintroduced Brook Trout generally have not moved outside of their release locations to occupy restored and/or newly-accessible habitats. Temperature monitoring has also indicated that restoration work, while improving connectivity, has had only minor impact on water temperatures so far. Two more dam removals further upstream on Sucker Brook are to be completed in the next 1-2 years with great potential for lowering water temperatures throughout the system and restoring access to additional coldwater habitat. This work is likely to have important implications as we continue to pursue broader restoration and conservation goals for coldwater streams in developed landscapes.
