During the summer, many Idahoans head to the water, but algae outbreaks can stop them from a relaxing day cooling off.

Algae blooms typically occur in slow-moving bodies of water, like lakes, but can occur in rivers as well. They can be harmful to human health and are especially dangerous for animals. Last year, it is suspected algae blooms led to the deaths of a horse and two dogs in Idaho.

Josh Johnson, central Idaho director for the Idaho Conservation League, said it is important to identify the toxic outbreaks, and to focus on what causes them.

"We don't often talk as much as about why are these happening," Johnson explained. "And some things we can't control, like it's going to be hot and sunny in the summer, but we can control the amount of nutrients that go into the water."

Johnson noted the origins of nutrient sources depend on the water body, but can come from agricultural runoff, waste from dairies and feedlots -- especially in southern Idaho -- or excess fertilizer on people's lawns. In the past two years, there have been 35 health advisories for algae blooms in Idaho.

Johnson pointed out states like Utah provide funding to track algae, but it is not the case for Idaho's environmental quality and health departments.

"This might be surprising to folks, given that this is a pretty big issue," Johnson stressed. "But right now, those agencies do not have any dedicated funding for toxic algae."

Johnson argued Idaho agencies are unable to get out ahead of the problem.

"There is no proactive monitoring of water bodies, even though we know the same water bodies, year after year, have toxic algae outbreaks," Johnson emphasized. "The agencies only have the resources to collect samples once a suspected outbreak has already occurred."

He added people can go to the Idaho Conservation League website to find ways to identify and report algae blooms.

A new study finds the autumn chore of raking leaves could be a disservice to budding plant life. The National Wildlife Federation found fallen leaves can be crucial to biodiversity. Experts find keeping leaves in a yard acts similar to mulch. They cover roots under plants, suppress weeds, and keep the soil moist. While the group's research finds this is common knowledge, only 25% of people surveyed said they actually leave the leaves.

Holly Shimizu, a board member with the American Horticultural Society, said for a lot pf people, it comes down to aesthetics.

"A lot of people, they love everything super neat and tidy, and if you're using leaves as your mulch, it's not going to have that same, like, totally tidy, neat look," she said. "It's going to be a little bit more natural looking."

But, she added the perception is slowly changing, as more people are working with nature in their gardens. The report reflects this shift as 82% of people surveyed are open to keeping leaves where they are to benefit wildlife.

While keeping leaves has benefits, there are limits to how well this can work.

David Mizejewski, a naturalist with the National Wildlife Federation, said a portion of the yard being covered with leaves can benefit wildlife, but leaving a couple inches of leaves on a lawn will kill it. Either way, bagging leaves is not a better alternative.

"Bagging them up and sending them to the landfill actually is a really bad thing," he said. "It really contributes some really nasty greenhouse gasses to the atmosphere that are a piece of climate change."

Mizejewski noted some states have taken action to keep leaves out of local landfills. The U.S. Composting Council finds 17 states have yard debris bans in place.

As more companies embrace sustainable practices, businesses in North Carolina are leading the charge through innovative initiatives with funds from the Inflation Reduction Act.

Brad Ives, former executive director of the Catawba College Center, seized on IRA funding to pioneer projects boosting the college's green initiatives.

"So the projects that we can do with the Inflation Reduction Act help us lower our emissions," he explained. "In particular, we're looking at Scope One emissions where we're burning natural gas or operating vehicles here on campus."

Ives added with the help of the IRA, the college has been able to work on projects such as replacing natural gas-fired clothes dryers and electric clothes dryers.

Ives suggested the IRA can greatly assist small businesses by offering financial aid programs such as grants, loans and tax incentives, making projects more cost efficient. He recommends companies start by connecting with peers, attending presentations and webinars, and staying updated on potential opportunities.

"Looking for RFPs to come out from entities like ours. We'll post from time to time that we've got an opportunity for somebody to come in and provide a good or service to us," he continued.

The IRA is estimated to invest over $21 billion in clean-energy tax incentives for North Carolina.

Vicki Lee Parker-High, North Carolina Business Council executive director, said the trend of more small businesses seeking to increase sustainability. She explained their organization is actively supporting members in exploring how the IRA can be beneficial across various industries, especially as environmental, social and corporate governance tracking becomes more important to companies looking to be more sustainable.

"We see that growing, and we don't see it slowing down anytime soon because we're seeing the larger corporations are starting to demand that the businesses along their supply chain also report and track their environmental and social impact," she continued.

Parker-High added the Inflation Reduction Act is proving to be a game-changer for small businesses in North Carolina, enabling them to actively contribute to environmental improvement while reaping financial benefits.

New research by ecology experts in Montana showed even small amounts of development can cause a widespread decline in stream biodiversity.

It does not take a new high-rise, bridge construction or freeway to have major effects on Montana's sensitive river and stream ecosystem.

Michael Sprague, founder and CEO of Livingston-based Trout Headwaters, said even small projects affecting less than 2% of a developed watershed cause significant loss of biodiversity in sensitive areas, and is especially harmful to aquatic life. It is evident in a number of ways.

"Diminishing vegetation, or peeling off topsoil or allowing excess erosion to occur on a site or some of these other things," Sprague explained.

Sprague added there are more chemicals winding up in rivers and streams now, too, which is also having a negative impact on waterway ecology.

Sprague argued even small roads and trails can have a major effect on biodiversity in Montana's waterways, often because roads are the first sign of development in ecologically sensitive areas.

"First of all, how is the road constructed? Is it stable? Is it eroding?," Sprague outlined. "Maybe you bisected a travel corridor for a species. Maybe you ran through some critical habitat or pushed that species off as a result of the road. Maybe that human access now by itself is causing migration."

Road building and development on environmentally sensitive lands remains an issue across the Plains states, where the ecology of rivers and streams is threatened, including on American Indian reservations.
