Will Your Avocado-Toast Push Monarchs to Extinction?

Post by our summer intern, Saige Patti!

Millennials may be giving up on the idea of house ownership as they spread their toast with creamy, delicious, green fruit – but are avocado lovers giving up on monarch butterflies?

Monarch populations have dropped by 90% since the 1990’s.

In the past, the decline in monarch populations has been largely correlated with loss of common milkweed – the only plant on which monarchs lay their larvae. Milkweed decline has occurred mostly in agricultural crops. The plants can’t survive contact with the chemical glyphosate from Monsanto’s Roundup pesticide. Agricultural milkweeds in the Midwest are significant: they have 4 times more monarch eggs than non-agricultural milkweeds, and in 2012 an 81% decline of agricultural milkweeds correlated with a decline 81% monarch production decline.

Unfortunately, declining numbers of milkweed plants are not the only thing affecting the monarchs.

A new threat has emerged: our beloved avocados.

While planting more milkweed and avoiding Roundup Ready GM crops are key steps to restoring habitat for monarch butterflies in North America, an increase in demand for avocados may annihilate crucial portions of their habitat in Mexico.

Popularity of avocados has surged in North America in recent years. With avocado being used for guacamole, sandwiches, smoothies, salads, pastas, and even desserts, it’s no wonder the versatile fruit is in demand. The market is also starting to expand globally; distributor Mission Produce Inc. is aiming to find ways of increasing avocado sales in China, which would greatly increase demand if it became popular.

The avocado business in Mexico is lucrative. With prices rising, it’s a good deal for land-owners to clear cut the forest and start growing crops.

The problem is that avocado crops grow in the same climate and altitude as the pine-oak forests which contain oyamel trees, or sacred fir trees. These are the trees on which monarchs spend the winter. When these forests were abundant, monarchs would overwinter in expansive areas of the sacred fir trees. Now, they cluster in a few groups of trees in the Monarch Butterfly Biosphere Reserve.

Oyamel forests are Mexico’s most endangered forest type with only 2% of the original forest remaining.

Monarchs are adapted to a delicate microclimate created by these forests, which changes when the forest is thinned or the perimeter is eliminated.

What is left of Oyamel forests is crucial to the survival of the monarch species.
Most of the butterflies overwinter in the Mexican State of Michoacán, where 20,000 hectares a year are converted for agricultural use, according to the attorney general's office for environmental protection. Avocados account for 30-40% of annual forest loss.

Deforestation as a result of avocado farming further adds to the effects climate change is already having on the forests. A 2012 study predicted that a changing climate could account for a 69.2%, decrease of sacred fir trees, and that increasing temperatures might require people to move trees 275m higher to cooler temperatures, and out of the Monarch Butterfly Biosphere Reserve by the end of the century. Additionally, trees are felled to create single-use crates in which the avocadoes are shipped.

Mario Tapia Vargas, a researcher at Mexico’s National Institute for Forestry, Farming and Fisheries Research, says that even where deforestation has not yet happened, there are areas with avocados growing in the understory. This alters the natural forest ecosystem and it’s ability to support wildlife. Tapia Vargas says it won’t be long before the forest around these crop trees are cut down as well.

With monarch populations already headed for extinction in the next 20 years based on milkweed decline, the effect of avocado crops would contribute even further to eliminating vast numbers of monarchs. This is dangerous, since small populations are more vulnerable to sudden environmental changes, which are increasing with the effects of climate change effects.

Additional loss of monarchs as a result of future avocado crops could quickly lead to monarch extinction.

Respect the Park: More than just a kid's playground.

Parks and wide open spaces need to be elevated to the highest levels of importance in our planning and budgeting process, reflecting their potential as an organizing principle, not as afterthoughts. Beverly Sandalack, Associate Dean, Landscape and Planning Environmental Design, University of Calgary.
Victoria Park, Hamilton.
Back in March, staff from the Pollinator Paradise project travelled to Calgary to learn about the role parks play in the city, for the 21st century. Heart of the City Conference (Shaping the future of city parks in Canada) (Park People) explored many functions of a public park--one of the main ideas being that parks, for many reasons, are the heart of a city.

Parks support green infrastructure.

We have challenges. Many challenges. With climate change comes high temperatures, droughts, flooding, and habitat decrease. But in our cities, we can do much to mitigate and adapt to these changes. Urban parks and open spaces have an enormous role to play in this respect.

Parks provide habitat, food and shelter for wildlife as well as trees which filter from air pollution and offer shade and comfort. When it comes to wide open spaces such as meadows, these are not generally thought of as being attractive or useful, unfortunately. But in the city, we need these spaces urgently because like urban parks they support local biodiversity.

Urban parks are important in the effort to create more resilient cities. They are green infrastructure that should be invested in. It's time to step up the role of parks as not just a playground for the little kiddies. We need to view parks not just as an add on, but as part of a complex system, incorporated into planning and design. We need to think of these spaces the way we do with natural areas – using a systems, multifunctional approach that can greatly contribute to increasing resiliency in the context of climate change and stormwater management.

Urban parks, open spaces, along with schoolyards, faith communities with outdoor space and even areas around parking lots can capture all stormwater from a given site as well as serve as a carbon sink, and reduce heat island effects (these occur when urban development such as buildings, roads, and other infrastructure replace open land and vegetation. Surfaces that were once permeable and moist become impermeable and dry. These changes cause urban regions to become warmer than their rural surroundings, forming an "island" of higher temperatures in the landscape).

Park as a public space
Parks have a long history as democratic spaces open to all in a city, acting as catalysts for interactions between people of different backgrounds and reducing intolerance.The contribution of local parks, Alexsandra Kazmierczak
There are not that many public spaces to gather in. The park therefore is an asset that ought to be cherished in any community. The potential for community involvement is massive. Not only as a way to engage residents in animating and using the park (animation is important, people need to feel there is a reason to go to a park), but also to make use of the public space on engaging residents around other issues.

At the conference, we learned about ways to "catalyze" the social impacts of parks including connecting people and reducing isolation. Park People (which is an independent charity that builds strong communities by animating and improving parks, placing them at the heart of life in cities) focuses especially on the work community members, municipalities and partner organizations in underserved neighbourhoods in recognition of growing inequality and the prevalence of neighbourhood-based inequalities. This is critical. We can't all go to the cottage or skiing, or camping, or hiking in Algonquin park. Newcomers, people of low income might not even have back yards. Of course, another main benefits of park spaces are social--reducing isolation and increasing connection between people.

Do More with our Parks.
Here in Hamilton, we are fortunate to be surrounded by much green space in general. How are we maintaining these spaces? what can we do better to increase engagement and make them more enjoyable to be in?
The City of Hamilton's The Adopt-a-Park program is a year round volunteer program where volunteer groups sign up to help maintain and care for trees, flowers and shrub beds in our local parks. Many groups hold events to promote park usage or fundraise for park enhancements such as benches, trees and play structures.

The City also has other programs for community members to get involved in, including the Community Clean Trailer and the Clean & Green Trailer which provides volunteers with the tools they need to beautify our city parks, alleyways, trails and neighbourhoods.

Our own Pollinator Paradise project has worked in many parks across the city to plant habitat and we plan to do more. In particular, we have been thrilled to work with Crown Point volunteers and residents to create habitat along the Pipeline Trail. A group that evolved from this work is the Crown Point Gardening Group. This wonderful group of gardeners share ideas as well as plants, and organize around other issues concerning their neighbourhood.

Resources
Park People have many great resources include Sparking Change, Catalyzing the Social Impacts of Parks in Underserved Neighbourhoods, and how to engage residents to participate.

Sparking Change has identified five different social impacts of park engagement: creating a sense of change and shared ownership, building confidence and inspiring civic leaders, reducing social isolation and creating more inclusive communities. providing a place for diverse people to gather and supporting local economic development. "Parks are not simply green places of respite--they are critical pieces of the social infrastructure of our cities. And we believe they have a role to play in creating more inclusive, equitable places that are shaped by and for the people living there."

Parks have massive potential for community development, according the the Sparking Change report. Think: social gathering space, recreation, cultural exchange, and of course, green spaces for habitat. Municipal spending on city parks still falls at the bottom of the queue when it comes to ranking the relative importance of a city's property tax funded services.
Their other resources include:

The Gothic Boat and Contemplations of the Pollinator Universe

Check out this beautiful piece by Monarch Awards' entrant, Calla Shea-Pelletier.

Chance is one important component in our garden. The beauty of it, entirely the collaboration of pollinators and humans. The placement and shape of a deck last year builds upon years of cultivating a theme of sanctuary. The gothic boat deck is suggestive of a human conveyance slowly moving through. It is an echo of the windows of the porch and the shape of the gardens. A subtle emphasis of the gothic theme, found in the choice of (almost) black and white plants, both native and non-native, punctuated with feature colours.

The lawn has been entirely replaced over the years, with the intention of cultivating pollinator gardens, pathways and rest stops.  Each year more opportunity for imaginative interactions unfold. The beauty we aspire to, embrace whimsy, multiple histories, and locations for foraging or refuge.

There is an abundance of inhospitable urban environments out there. If beauty is also compassion, our efforts bring together communities of plants, creatures and human built environments for gentle collisions to contemplate the pollinator universe.

Poem inspired by a seven year old, who volunteered this information:

“I want to be a pollinator,
I will carry small brushes with me”
she said making the motions
of pollinating with tiny instruments.
In the moment I understand,
she is compassion itself,
“I hope you won’t have to live in a world
where such a job is necessary”, I say
fearing that she already did.

Urquhart Butterfly Garden: Summer Series and Competition

Clouded Sulphur 2016 Photo by Michelle Sharp

We love sharing pollinator-supportive events in our community, so we are excited to let you know about the free Summer series at the Urquhart Butterfly Garden.

The series kicks off on Saturday July 15 with Matt Mills leading a Guided Butterfly & Bird Identification Walk.  Matt is an experienced naturalist, with a vast store of knowledge and an engaging manner.

The Garden is humming with life, “I am never disappointed by what I see at the Urquhart Butterfly Garden,” Matt said recently. If there are rare butterflies to be seen Matt will find them, as well as locating all the bird life hiding in the bushes or flitting among the trees.

The Guided Walk takes about an hour and begins at 11 am on Saturday, July 15. You are requested to wear a sun hat and bring a chair.
If it rains the walk will be cancelled.

The Summer Programme will be held every Saturday until September 2.
The Urquhart Butterfly Garden is located at the end of Centennial Park in Dundas. All ages are welcome.
