Bob's Curated List

My Favorite Resources & Sites

These are the people, organizations, and tools that have shaped how I think about native habitats, ecological design, and the living world. I return to all of them regularly. Every link here is a genuine recommendation — not a list, but a library.

Bob RecommendsDocumentary Film · 2017 · Directed by Thomas Piper

Five Seasons: The Gardens of Piet Oudolf

Piet Oudolf · High Line · Lurie Garden · Hauser & Wirth Somerset

If you want to understand what a living landscape truly means — not just intellectually, but in your bones — watch this film. Thomas Piper follows Piet across five seasons and somehow captures something that most garden writing never does: the feeling of a place that is fully, quietly alive.

I've watched it more times than I can count. It keeps getting better. Every time I return to it, I notice something I missed — a gesture in the planting, a quality of light, a moment where Piet says something that reframes everything. It is, without question, one of the most beautiful films ever made about what a garden can be.

Design Visionaries

The People Who Shaped the Vision

These are the designers, scientists, and thinkers whose work runs through every WBDS habitat. Not influences in the abstract — influences in the literal sense. Their ideas are in the ground.

Conservation Movement

HomeGrown National Park

Doug Tallamy · University of Delaware

The grassroots movement co-founded by Doug Tallamy that is turning private yards into a connected network of native habitat. Every property that converts from turf to native plantings becomes a node in the largest wildlife corridor in America. This is the science behind everything WBDS does.

Landscape Design

Adam Woodruff LLC

Plant-Driven Landscape Design · St. Louis, MO

Adam works the way WBDS thinks — from the plant outward. His landscapes don't impose a design on a site; they listen to it. Every planting is atmosphere-focused, site-responsive, and built to evolve. When I look at his work, I see what a layered living system looks like when it's also deeply beautiful.

Garden · Art

Oudolf Field at Hauser & Wirth

Piet Oudolf · Bruton, Somerset, England

A 1.5-acre perennial meadow designed by Piet Oudolf on the grounds of a former Somerset farmstead. It is one of the most quietly extraordinary places in the world — a living demonstration that a landscape can be both a work of art and a functioning ecosystem. If you ever find yourself in England, go.

Public Garden

Piet Oudolf — Lurie Garden

Millennium Park · Chicago, IL

Five acres of native and naturalistic perennial plantings in the heart of Chicago. The Lurie Garden is proof that the New Perennial Movement isn't just for private estates — it belongs in cities, in public spaces, in the places where the most people can encounter it. Oudolf's masterwork in America.

Conservation & Local Ecology

Organizations & Practitioners Doing the Work

The people and organizations on the ground — protecting land, documenting wildlife, and building the tools that connect homeowners to the native landscape.

Education & Science

Resources Bob Sends People To

When someone asks where to start learning, these are the resources I point them toward. Rigorous, accessible, and genuinely useful — whether you're a first-time homeowner or a professional ecologist.

Science · Tools

Audubon — Grow These Plants for Wild Birds

National Audubon Society · Native Plant Database

Enter your zip code and Audubon's database returns the native plants that support the most bird species in your specific region. It's one of the most practical tools available for homeowners who want to make evidence-based planting decisions. Use this before you buy a single plant.

Science · Research

Cornell Lab of Ornithology

Cornell University · eBird · Merlin · All About Birds

The world's leading source of information about birds — from the Merlin ID app to eBird's global sighting database to All About Birds' species accounts. If you want to know what a bird needs to survive, Cornell has the answer. This is the science that informs every WBDS habitat design.

Horticulture · Education

Rebecca McMackin

Ecological Horticulture · Design & Education

An ecologically obsessed horticulturist and garden designer who manages landscapes for both people and wildlife. Rebecca's writing and lectures bridge the gap between rigorous ecology and practical garden management in a way that very few people can. Her work on the Brooklyn Bridge Park gardens is exceptional.

Habitat · Conservation

Young Forest Project

Early Successional Habitat · Wildlife Conservation

A science-based initiative promoting early successional habitat — young forest and shrubland — for the wildlife species that depend on it: American Woodcock, New England Cottontail, Golden-winged Warbler, and dozens more. A critical and often overlooked layer in the full ecological picture.

Craftsmanship & Design

Accoya Wood Garden Elements

Bob designs custom garden elements that go beyond the landscape itself — planters, boxes, and built features that become living parts of the habitat. These pieces are expertly crafted by local master woodworker Dave Thal, owner of The Wood Shop in Malvern, PA — from Accoya wood, a sustainably sourced, FSC-certified timber that weathers naturally to a beautiful silver-gray without staining or treatment. More durable than teak, more sustainable than cedar, Accoya is the right material for pieces meant to last decades in the field.

Why Accoya Wood?

Accoya is a modified timber — acetylated to make it dimensionally stable, rot-resistant, and inhospitable to insects, without the use of toxic chemicals. Left untreated, it weathers to a soft, natural gray that complements any garden. It carries FSC certification and is widely regarded as one of the most environmentally responsible hardwood alternatives available. For outdoor garden elements that live in the landscape year-round, it is simply the right choice.
