Tul Forests for Lake Atitlán

Raised by 97 people in 22 months

Lake Atitlan, Guatemala — which Lonely Planet calls “the closest thing to Eden on Earth" — is in desperate need of remediation due to wastewater contamination and chemical agricultural runoff. We at Lake Atitlán Environmental Interests Group are asking for your support to help reforest the lake with the Tul plant, which is a natural filter of pathogens and absorbs excess nutrients to promote a healthy ecosystem.


Lake Atitlán sits in a volcanic crater and has no outflow, so everything that goes in, stays in. This includes wastewater from at least 20 towns and chemical fertilizer and pesticide runoff from chemical agriculture. The scientific agency in charge of monitoring Lake Atitlán (AMSCLAE) says that without immediate action the Lake will be unrecoverable within 7 years.

Beyond destroying its natural beauty, the contamination threatens the livelihoods of those who live by the Lake's waters (due to less tourism), as well as negatively affecting the health of the 200,000 people who use the Lake for their drinking water (roughly 20% of the population suffers from e-coli, amoebas, giardia, and other intestinal pathogens) . Tul helps to create a protective barrier along the shores and filter out pathogens and nutrients before they reach the Lake.

LAEIG is organizing a Tul Reforesting again for February 3rd and 4th for Tzununa.  As of today (1/19/2017) the funding from this campaign has put over 2500 Tul plants in the water!!!!!!

Every $25 donation lets us add 10 Tul plants to the Tul Forests. That pays for the plants, 20 stones to anchor the plants, some rope, and expert help from local Mayan Tuleros, to make sure the plants thrive. Our goal is to raise $1,250 to support the planting of 500 Tul plants for our Dec. 3-4 planting and take a significant step forward in saving this natural treasure that is certainly close to your heart if you live here or at the top of your bucket list!

Guatemala is infamous for corruption at all levels of government. Officially supplied funds simply cannot reach projects like these with any efficiency and the situation is urgent. We cannot wait for bureaucratic solutions. We must take action now to Save Lake Atitlán.

Local citizens are ready and standing by to help Save Lake Atitlán, but we depend on the international community to come up with the funds. The citizens of Atitlán know that by working together and enlisting the help of a global community of people who care about our Mother Earth, we can save Lake Atitlán.


Phytoremediation is a natural, low-cost, solar-energy-driven cleanup technique that puts living plants in place to decrease contaminants in water and soils. 
LAEIG members believe that phytoremediation is the quickest and least expensive way to help Lake Atitlán survive. Phytoremediation Projects help to mitigate the effects of the constantly increasing pollution, keeping the Lake alive while other systems are implemented that deal with the nutrient and pathogen problems at their sources.

We have identified three phytoremediation projects as the best and fastest ways possible to increase the filtering of pathogens and removal of nutrients from the Lake.


Tul is a native plant that grows along the shores of Lake Atitlán.  It grows rapidly and in the process absorbs nitrogen, phophorus, and other undesirable nutrients from the water.  It becomes covered with a biofilm of bacteria that converts even more nutrients and filters the water that passes by.

Tul is one of the most important plants in the Lake for filtering pathogens (the biofilm growing on each plant)and absorbing excessive nutrients and preserving a healthy ecosystem. It serves as a home for fish, frogs, and other aquatic animal life as they grow and reproduce, maintaining healthy populations for the local communities that derive food sources from the Lake.

Tul is also used by the local Mayan craftsmen to make various products that they sell locally and export to foreign markets. Tul provides a critical source of income for many local families.

Several years ago, Lake Atitlán experienced an excessive loss of Tul forests due to a significant rise in water levels caused by an abnormally heavy rainy season. That was a double "punch to the gut" for Lake Atitlán. Not only did excessive amounts of nutrients wash into the Lake, triggering a cycle of recurring algae blooms, but also the Lake's natural defenses against contamination were severely damaged by the loss of Tul Forests and their natural filtrating actions.

Efforts have been underway ever since to reforest the Tul around the Lake and restore the natural filtration systems. Due to the impending crisis that Lake Atitlán is facing, it is vital that as much Tul as possible be restored to mitigate the effects of the constantly increasing pollution.

LAEIG is gearing up to implement floating gardens in Lake Atitlán. Rafts covered with soil and plants will be anchored in the Lake to create floating garden "wetlands" that clean the water. The plant roots grow through the raft bottom into the lake, where they absorb nitrogen and phosphorous. Bacteria create a biofilm on the raft and roots that consumes nitrogen and phosphorous, converting them to less harmful substances.

Pollutants such as metals and particulates are also filtered out, since suspended solids bond to the biofilm. This makes the water clearer, which lets light penetrate deeper, thereby letting plants grow deeper, bringing oxygen deeper. Organic matter that attaches to the underside of the floating islands provides food for fish, and the islands provide habitat for birds. Planting floating gardens with commercially valuable plants can increase the impact of this project.


In this Phytoremediation project, floating rings will be placed in the lake, and the interior filled with water hyacinths. Water hyancinths are extremely fast growing, absorbing nutrients quickly and their roots hang down up to a foot below the surface creating a huge floating filtration area. Every couple of weeks, about half are harvested for use in composting operations to improve organic farming in the Lake Atitlán area thus removing nutrients from the lake and converting those nutrients into high quality organic compost for native farmers.


The Lake Atitlán Environmental Interests Group is an all-volunteer organization. We work in association with volunteers from many other organizations. LAEIG's nonprofit and NGO statuses are being processed, and meanwhile we are working full speed ahead.

This week we will be meeting at the Tzununa dock at 8 o'clock. If you can't make it by 8 o'clock we will be planting around the point to the right (if looking from the dock out to the lake). The same area we planted last month, just a little further around the corner.

We need your help to raise the final @ $800 to close this campaign out. What has this campaign accomplished?

1. We have planted probably close to a mile of shoreline in about 40 different plantings around 6 of the towns.

2. We have generated an incredible amount of awareness included being featured in National newspapers 8 times, on National TV 4 times and on the upcoming UNESCO Documentary.

3. We have brought together hundreds of volunteers, local schools, several government agencies, numerous NGO and Rotary groups in collaborative efforts to work together for a common cause.

4. Critical contacts within local communities and government agencies have been developed.

5. Built a core group of people with a burning desire to help save Lake Atitlan and the ability to work together with others for that common goal.

6. The MAJOR problem of the tilapia farms is now being investigated and denounced.

7. The boat to support further plantings repair is underway.

.........and quite a bit more......Not too bad for a few thousand dollars and a ton of hard work.........

Together we have accomplished quite a bit! Let's finish up this campaign and keep working hard!
Great community support
This beautiful Lake........

A reminder that we will be planting in Santa Cruz this Thursday at 8 a.m.. Same place as last week.
+ Read More
Just a couple more days until Santa Cruz so sending out a reminder:

1. Meet at 8 a.m. Thursday morning at the public dock. If you can't be there by then we will be off to the right (right when facing town from on the lake) in the big sandy area.
2. We haven't had any volunteers for bringing snacks.....
3. All logistics are taken care of.
4. Anyone want to contribute anything in particular or flag a donation for a certain contribution? (snacks, drinks, something else to show our appreciation for all the hard work......)

See y'all in Santa Cruz!

Here's a few pics of the Tuleros planting another exposed point in Santiago bay today. If it seems like we plant in Santiago a lot more then the rest of the lake, well, that would be accurate. It's so much simpler to do there due to the fact that we just hire the Tuleros to do it. They bring the Tul and no stones are needed (which moving stones, securing stones to the tul, carrying marcolas, etc is 80% of the work). It takes 30 minutes to do 150 plants when we don't have to do all the stone work whereas it will take us hours and dozens of people to do the same amount in the rest of the lake.

I love seeing the tul and I'm SO happy to know that there are many wonderful people who are planting it. I hope that more people will join this good core of environmental activists and that this GLORIOUS LAKE can be saved!!! If Lake Erie an Lake Michigan were worse in the '50s before activists (Pete Seeger, of blessed memory was one of them) began to get more people first aware and then involved ... it CAN be done here, at a much smaller lake!

Thank you. I cannot physically go into the lake to plant Tul at this time, BUT I CAN MAKE A DIFFERENCE by sharing some money to help make it possible. If every lucid person will just do whatever they can to help financially (and in person!), the Lake can be preserved and renewed. If we don't do it, who will?
