Sharing insights from DiPrete’s Environmental Services leader, Tim Twohig

We’re excited to launch the first edition of From the Field with Tim, a behind-the-scenes look at the wide range of environmental science work happening across New England with DiPrete Engineering. With 15 years of experience as an educator and over six years in his role at the firm, Tim Twohig, PWS, CPSS, leads DiPrete’s Environmental Services department. Through his fieldwork, Tim documents the conditions that shape our projects – from wetlands and soils to plant life and wildlife – and shares those insights on LinkedIn in a way that blends technical expertise with genuine interest in the natural world.
Tim’s posts offer a glimpse into the many facets of Environmental Services, including:
Wetland Delineation
- Wetland delineations that support local approval processes.
Soil Science in Action
- Field investigations that reveal how soils form and function, and how factors like landscape position, water tables, and seasonal change influence site conditions.
- Continuing education and collaboration with professional peers to stay at the forefront of best practices.
Rare and Invasive Species Discoveries
- Highlights from site visits where Tim identifies and documents both state-threatened plants and invasive species, helping inform project design and permitting.
- Memorable wildlife encounters, like close-up hummingbird footage, that capture the beauty of New England’s ecosystems.
Tree and Plant Identification
- Tree inventories and practical tips to help others recognize key species and understand their environmental significance.
These updates reflect Tim’s depth of knowledge and the expertise he brings to every project. To stay connected with his latest field insights, follow Tim on LinkedIn.
