March 2022 EcoQuest: Wildflower Wonders: Round 2

Join the March EcoQuest: Wildflower Wonders: Round 2.
Find and map as many wildflowers as possible.

Wildflower season is a cherished event in the Sonoran Desert. Blanketing the desert floor with impressive shapes and colors, these ephemeral wonders have specific requirements to flourish. Observing wildflowers can provide information on populations as well as environmental conditions and the effects of climate change. These observations can also provide an artistic appreciation of these natural wonders.

Join the EcoQuest
Guide to Wildflowers of Metro Phoenix


WHAT TO OBSERVE:
Any and all wildflowers in metro Phoenix. Wildflowers are flowering plants that grow without human intervention and only make an appearance for a season. Be sure to take multiple photos and include as many details as possible for an observation.



This month’s EcoQuest is in collaboration with Peoria Parks and Recreation’s Wildflowers of Peoria BioBlitz.

Let's work together! Are you ready to help Peoria document and learn about the many different wildflowers that grow in its preserves and trails? Located about 30 minutes northwest of downtown Phoenix, Peoria is a modern city that offers a high quality of living in the natural beauty of the Sonoran Desert. Peoria's Parks and Recreation Department manages access to 570 acres of parks including 36 neighborhood parks, three large community parks, more than 60 miles of hiking, biking, and horseback riding trails, and Lake Pleasant.
Join the Peoria BioBlitz.


We’re diving in for a second round of wildflower observations. Last year, there were hardly any wildflowers- most likely due to extreme drought and the late timing of very little rainfall. We’ll compare last year’s observations to what we observe in this month’s EcoQuest. This can provide us a understanding of wildflower phenology in the area. Phenology is nature’s calendar, that is cyclical and seasonal changes in biological life cycles. Climate change effects, like extreme drought, can alter normal phenological cycles. Learn more about phenology with the National Phenology Network.

The spring wildflower displays of the Sonoran Desert are one of the most anticipated natural events of the year. Native shrubs, perennials, annuals and even trees contribute to our wildflower bloom, but we typically think of wildflowers as annual plants, such as poppies and lupines, that appear briefly in the spring. Annuals complete their life cycle in one season, putting a tremendous amount of energy into quickly completing their life cycle. Many germinate, flower and die in just a few weeks. This strategy allows these plants, also known as ephemerals, to take advantage of short wet periods.

Annual wildflowers usually need a soaking rain of at least one inch in the fall. Earlier and more plentiful rains tend to create super-bloom displays. Temperature also plays a role. The plentiful rain should ideally come after the heat of summer, but before the coldest parts of winter. If these conditions aren’t met, wildflowers will produce fewer flowers and seeds, just enough to support future generations. Some species’ seeds can persist in the soil for up to 10 years, providing more insurance for their survival. Because rain is unpredictable, a good wildflower bloom may only occur once in a decade.

When making wildflower observations, take a moment to get closer and inspect their structure. Look at the petal shapes, textures, color combinations and pollen colors. What small details can you see that you may have overlooked before? Slowing down and getting closer can increase our artistic appreciation for wildflowers. On March 22, artist Linda Arandas will be sharing her tips and techniques used to embroider a variety of Arizona wildflowers. No experience is necessary and supplies will be provided. Let your creativity bloom as you learn a new skill and create your own beautiful work of art!

Observing wildflowers can provide information on populations and how environmental conditions and climate change, such as lack of rainfall, extreme temperatures or longer periods of heat, could be affecting phenology. These observations also give us a chance to slow down and appreciate the artistic characteristics of these short-lived wonders.

PLEASE RESPECT WILDFLOWERS. Picking one wildflower might not cause any harm, but it is important to realize that you may not be the only person. The combined effect of 50, 100 or 500 people picking wildflowers could devastate populations. With recent droughts and fires, wildflowers need their seeds to ensure we have blooming populations in the future. It is also illegal to remove wildflowers without a permit from public lands like state and city parks. Private land is also off limits unless you have permission.

Treading, sitting or lying on wildflower habitat is also a problem. Doing this in a wildflower patch can crush existing plants and compact the soil, making it more difficult for wildflowers to get started. This is especially true with repeated use and treading. Stick to the trails and take responsible wildflower selfies.

QuickQuest: Catch Cape Marigold!

Join us for a QuickQuest: Catch Cape Marigold, from March 17-31.
Find and map as many Cape marigolds (Dimorphotheca sinuata) as possible.

Join the QuickQuest



WHAT TO OBSERVE:
Scientific name: Dimorphotheca sinuata
Common name: Cape marigold, African daisy

See it on SEINet
See it on iNaturalist



Native to South Africa, Cape marigolds (Dimorphotheca sinuata) have been making an appearance in metro Phoenix since the early 1960s. Also known as African daisy, this annual flowering plant is often mistaken for a native wildflower. Their seeds are included in some wildflower seed mixes and this is likely how they were introduced to our area. They have escaped cultivation and have become naturalized (growing a sustainable population on its own) in some areas. They can be found far out in wilderness, as well as nearby urban areas. Cape marigold is now regarded as an emerging invasive species in California and Australia. The term "invasive" is used for aggressive species that grow and reproduce rapidly, displace native species, and can alter ecosystems. In recent years, iNaturalist observations of this plant have been increasing in metro Phoenix, growing from 1 observation in 2016, to 62 observations in 2020. In 2021, there were 28 observations, likely due to the extreme drought. The increase in observations could be attributed to more people using iNaturalist or simply because more people are noticing and recognizing these colorful flowers. We need your help to learn more!

By observing and mapping Cape marigolds, we can learn more about their population growth and spread. Are they competing with native wildflowers and do they have invasive potential in our area? You can help us find out! Observations of large groupings of this plant are especially helpful.

April 2022 EcoQuest: Imprudent Pruning

Join the April EcoQuest: Imprudent Pruning.
Find and map as many examples of improper pruning as possible.

🚨Be sure to use #imprudentpruning in the notes of your observation! This will help us sort through the observations on iNaturalist.🚨

Join the EcoQuest

WHAT TO OBSERVE:
Any and all example of improper pruning in metro Phoenix, including trees and shrubs, palms, cactus and agaves. Take multiple photos and include as many details as possible with observations.


This month’s EcoQuest is in collaboration with Desert Botanical Garden’s Desert Landscape School.

Desert Landscape School (DLS) is a signature program at Desert Botanical Garden, that offers professionals, homeowners and gardeners an opportunity to learn from experts about all aspects of desert landscaping. Sign up for one of the exciting horticulture and desert gardening classes today! Courses are available for online and onsite learning. Learn with DLS.

To learn how to properly prune and maintain plants, take the DLS Planting and Maintenance class, starting the week of April 18th.



Ragged cuts that will not heal well, if at all.

In nature, plants can be pruned by animals, storms, or they naturally shed branches. In a landscape setting, like homes and urban areas, pruning can be done for various reasons. Choosing the right plant for the right place should always be the first consideration. This means choosing plants that will not outgrow the space they’re in, cause problems when fully grown, or need a lot of pruning. There are multiple types of pruning -thinning, structural, or raising- that can help maintain plant health, influence fruiting and flowering, provide clearance or improve aesthetics when done properly.

Imprudent pruning is asking for trouble. When pruning practices and methods aren’t carefully considered and executed, it can affect the health and life of plants. Improper pruning can damage a plant for the rest of its life. Pruning reduces and removes plant resources, creates wounds, and causes plants to react in different ways. The use of dirty and dull tools also can cause damage and spread disease. Removing too much plant material at once can shock plants and weaken them. Pruning at the wrong time can reduce or eliminate flowers and fruits, reducing food sources for pollinators and wildlife.

Plants provide many benefits to people and wildlife, and help mitigate the effects of climate change. If we are planting trees in great numbers but are losing them in a few years’ time due to improper pruning and maintenance, we are negating our efforts. Mature trees are less tolerant of pruning, and we can lose them and the many benefits they provide to harsh pruning practices. It is important to maintain plants for the long-term.

Below are the top 5 most common examples of imprudent pruning. Can you find these for this month’s EcoQuest?


TOP 5 NOT WANTED:

Topping

What is it? Literally cutting off the top of a tree, across branches with no consideration for proper pruning cuts.

Effect: Removing the top of a tree causes compounding problems. Immediately, this depletes the resources of a tree and causes an immense amount of stress. As the tree attempts to recover, multiple new branches will grow from the exposed cut stubs. These branches compete with one another, leading to poor branch connections that can eventually break. Exposed stubs can rot and lead to even more damage. Topping, especially repeatedly, is a slow death for a tree. In depth info can be found here.

What to do instead: Right plant, right place. Selectively prune branches. Larger limbs can be pruned back to a lateral limb that is at least on-third the diameter of the limb being removed.


Lion Tailing

What is it? Removing interior branches, leaving a “tuft” of branches on the outer-most ends, resembling a lion’s tail.

Effect: Trees naturally grow in a way that evenly distributes weight. Lion tailing concentrates the weight of branches left at the top, leaving the tree’s structure compromised. Especially when combined with new growth, the concentrated weight becomes too much for the tree to handle, causing the tree to break or split. This also leaves a tree more vulnerable to storm damage.

What to do instead: Right plant, right place. Selectively prune branches. For trees that have previously been lion tailed, allow sprouts along the lower branches to fill in and selectively prune them with time to create more stable branching.


Shrub Shapes

What is it? Also known as meatballing, shearing, or tipping, this is cutting the tips of branches off to shape a shrub and removing large amounts of the plant all at once. Shearing cuts are made all over, without taking the structure of the plant into consideration. Shrubs are often sheared into unnatural geometric shapes.

Effect: Removing the tips of branches stimulates growth and density. This in turn blocks sunlight to the interior of the plant, reducing its ability to photosynthesize. While the outside might look green and healthy, the inside is browning and unhealthy. This can eventually kill the plant from the inside out.

What to do instead: Right plant, right place. Selectively prune branches for size and structure, according to selected plant and desired size.


Puny Palms

What is it? Over-pruning palm trees, leaving very few living fronds.

Effect: Palm trees rely heavily on their fronds to make energy, and they typically only make a few fronds at a time. Some only make one to two new fronds a year! Removing living fronds can slow or stop a palm’s growth. Over-pruning palms also makes them less storm tolerant. Climbing spikes should not be used to climb palms to prune. Climbing spikes wound the palm tree which do not close, inviting insects and pests.

What to do instead: If you must, only remove dead or discolored fronds, never living fronds. Do not remove fronds that have a horizontal or upward orientation.

Cactus and Succulent Chop

What is it? Randomly chopping cactus, cutting agaves to look like pineapples, trimming up or “skinning” yuccas, shearing aloes.

Effect: Excessive pruning can harm and kill cactus, agaves, aloes and yuccas. Removing leaves from agaves, aloes and yuccas makes them more vulnerable to cold and water loss. Pruning wounds plants, opening a pathway for disease and pests.

What to do instead: Right plant, right place. Agaves, aloes, and yuccas retain dead leaves and should not be pruned. Do not remove living leaves. If necessary, flowering and fruiting stalks can be removed. Cactus and succulents should be pruned at a joint or line of demarcation. Right plant, right place. Do not plant near walkways or other areas frequented by people and pets.


Does all of this sound complicated? Don’t worry, because it is! Pruning and plant maintenance is a science and takes knowledge and experience. Pruning and landscape maintenance should be done by certified arborists and landscapers with training and a strong understanding of plant biology. They know what will improve the health of your plants and help them last.

The City of Glendale has some great resources to help you get started. Visit their Arizona Friendly Landscaping page here, and check out their helpful pruning video.

Observing plants that have been imprudently pruned can help us recognize improper pruning and the effect it has on the health and longevity of plants. We can also see if there are patterns of improper pruning in our area.

Tell your friends! Say NO to the top 5 NOT wanted!



PRIVACY GUIDELINES

When making observations, please be mindful of homeowners’ yards and commercial properties. Do not include identifiers of homes or businesses in your photos. That includes submitting observations with the name of a company, home address, etc.. Photos that don’t follow these guidelines will be removed and will not count for the EcoQuest..
