In North America, invasive plant species – non-native plants that spread aggressively and disrupt natural habitats – cost over $26 billion annually. Unlike native flora that co-evolve with local ecosystems, these invaders outcompete indigenous plants, degrade soil health, and alter fire regimes, ultimately undermining entire ecosystems. They also create ripple effects that harm economies and even human health. That staggering figure highlights the urgency, grabs attention, and sets the stage for a powerful narrative about conservation action.
A Conservation Career with Real-World Impact
Zachary Nowak, a former Boone and Crockett Fellow whose work blends wildlife science with public policy. After earning dual degrees – B.S. in Wildlife & Fishery Sciences (2019) and a Master in Public Service & Administration (2021) from Texas A&M – Nowak led a capstone project documenting every invasive species in Nevada (80.1% federal land) and Texas (1.9% federal land). The number of invasives corresponded directly with each state’s land ownership breakdown – a clear, concrete result that illustrates the scale of the challenge.
Today, Nowak works as a policy advisor with the Western Governors Association, guiding a bipartisan team across 22 governors in 19 states. He monitors federal policy, synthesizes stakeholder info, and leads the Western Invasive Species Council. This multi-state collaboration unites experts to strategize, share intel, and shape targeted management efforts – offering a template for real progress.
Precision Translates to Outcomes
Nowak’s transition from thesis leader to policy influencer shows how clear-eyed goals yield concrete results. By compiling a federal law inventory on invasives upon starting in 2022, he created a baseline that directs future legislation. His leadership on the Western Invasive Species Council cements the foundation for collective action.

What Readers Should Walk Away With
- Fact: Invasive plant species – like cheatgrass, tamarisk, and yellow starthistle – are not just eyesores; they crowd out native vegetation, increase wildfire risks, deplete water resources, and cost North America over $26 billion every year in management, damages, and lost productivity.
- Takeaway: Tackling invasive species isn’t just about pulling weeds – it requires strategic collaboration across science, land management, and policy. Zach Nowak’s work shows how documenting species distributions, analyzing land ownership patterns, and building coalitions like the Western Invasive Species Council can drive smarter, faster action across state lines.
- Conversation Starter: “Did you know that invasive plants like cheatgrass can turn entire landscapes into fire-prone zones – and that scientists and governors are now working together to stop them?”
By turning complex ecological problems into clear policy priorities, this story shows how conservationists can shape the future of land stewardship – not just in theory, but in practice.
