    Vision

    A “PASSIVE, NATURAL, EDUCATIONAL, NEIGHBORHOOD RETREAT” 

    Mission

    Atlanta is the City in the Forest, but how many people are able to easily visit an actual forest? Our mission is to restore this 5 acre riparian forest situated on the Atlanta Beltline in Louise G. Howard Park and to provide a passive, natural, educational, neighborhood retreat. 

    Location details

    Fulton County Property Parcel 17 0146 LL0034 

    Land use code 610-Recreation/Health

    History

    The area we call Cathedral Woods became a county park in 1938 as part of the same parcel that makes up a portion of Tanyard Creek Park. (Tanyard Creek Park was expanded in 1951 with an additional parcel.) Cathedral Woods is located east of Tanyard Creek, north of Collier Road, and south of Bobby Jones golf course. The entrance is at the intersection of the Atlanta Beltline and the Beltline Connector to Bitsy Grant Tennis Center. Old maps show the Cathedral Woods area as simply "Fulton County park" as it was not part of the city until annexation in 1952. Recently, it is being referred to as part of Louise G. Howard Park, although that park was not acquired until 2006. The city parks department has included it in Louise G. Howard Park in their master plan (see https://www.atlantaga.gov/government/departments/parks-recreation/equity-data-tool). 


    Louise G. Howard Park is adjacent to Cathedral Woods, on the other side of Tanyard Creek. When this property was redeveloped as a park (circa 2008), a Master Plan was created. An early draft is published here and a final draft below. Central to this master plan is "to return this residential property to closer resemble its original  native state." For Cathedral Woods, we have adopted the vision from the Louise G. Howard Master Plan which is a “PASSIVE, NATURAL, EDUCATIONAL, NEIGHBORHOOD RETREAT” 


    Cathedral Woods being too close to the creek and in the flood plain, has not been developed or farmed at least as far back as 1825 when the property was acquired from the Muscogee (Creek) Nation. It is, therefore, old growth forest. 


    In 2013, a common persimmon tree was nominated for champion tree. In 2009, a tree survey was conducted as part of the Beltline project - see drawings below. When the Beltline trail was built, the City of Atlanta Parks Department hired a contractor to clear invasives from both sides of the creek. The western side of the creek is maintained by the city and volunteers, but the eastern side has reverted to its previous poor condition. Every few years, neighbors attempted to remove privet and cut ivy from the trees. But it just grows back. 


    At the end of our first year of forest restoration (2024), we had started restoration of approximately 1 acre and developed a small nature trail.

    1 year anniversary highlights (fall 2023 – 2024)

    Biggest pleasant surprise: Bloodroot

    This beautiful forest floor plant showed up in the spring in an area we cleared of English ivy last fall. We hope we’ll see more next spring now that we’ve cleared a lot more area.


    Why is it good?

    Spring ephemerals are small, delicate wildflowers that bloom in the spring before trees leaf out. They are important members of the forest community because they provide a vital early food source for emerging insects. They also convert plant material into protein-rich nutrition for larger animals. 

    Bloodroot is so named because a damaged root will ooze a red sap. The red sap was used by Native Americans as a dye and insect repellent. CAUTION: The sap is an irritant, and the rhizome (thickened underground root) is poisonous and should not be eaten. 

    Biggest Challenge: Japanese Chaff Flower

    After several years of unchecked spreading, the seed load along the edge of the forest is high. It takes repeated efforts to eradicate.


    Why is it a problem?

    This invasive species outcompetes native species and forms large, dense stands in floodplains, forested wetlands, ditches and other disturbed edge habitats. This mono-crop density prevents natural biodiversity from thriving in areas that would naturally contain very high pollinator abundance. Dogs (and people) are spreading its hitchhiker seeds along all the trails.

    Biggest impact: removing Amur Honeysuckle

    This invasive shrub had spread widely in the woods, so removing it let in air and freed up a lot of space for natives to thrive.


    Why is it a problem?

    This invasive species can alter a habitat's microclimate, by creating dense shade, depleting soil moisture and nutrients, and possibly releasing allelopathic chemicals that inhibit growth of other plants. It can be especially harmful to spring ephemerals, due to its early leafing. 

    Frequently Asked Questions

    1. Why are you creating a nature trail? Isn't it better to leave it as an inaccessible wildlife corridor? ANSWER: The leaders of this project believe that only by creating a love for this space will we be able to generate the will and resources to maintain the space. The trail will not cover the entire 5 acres, but will provide some access so that people can discover interesting plants and wildlife and learn what a healthy forest looks like. Letting people come in there will have risks beyond the animals. They will undoubtedly bring in seeds of invasives, which will create more work for us. But everything in life involves trade-offs, and there is no perfect solution.  People who have lived nearby for a long time lament the loss of wildlife that happened when the Beltline was built here. They fondly remember a den of foxes that hasn't been seen in a long time. There was a similar concern when the golf course was redeveloped and many trees were cut down. In spite of that, there is a barred owl that nests in a tree near the bottom of the stairs in Louise G. Howard Park. Deer are frequently seen. A coyote recently nabbed a neighbor's cat. The beaver that lives upstream survived the 2022 CSX railroad bridge replacement, and even had a kit in the spring of 2023 in spite of all the disruption. It is amazing how wildlife finds a way! We are cognizant of the need to provide food and shelter. This is why we are letting the piles of removed material mulch in place. We don't intend to make this look like someone's landscaped yard. And we will be encouraging the growth of native plants to provide food. Beyond the animals, there are forest floor plants that are native. In the first small area we cleared (fall 2023), bloodroot emerged and bloomed in the spring. There is still some trillium back in there. One neighbor rescued a large batch of trillium that was located where the Beltline was built. He still has it in his backyard and is interested in repatriating it to the woods at the appropriate time. Our hope is that by walking in there, you too will get excited about this space and support our efforts.
    2. Is it being done without any herbicides or when/why do you use them? ANSWER: We are mostly using hand tools and manual labor. But there are a few times when it is much more efficient and effective to use a very small amount of herbicide. "Cut and treat" is an approved method for removing invasive shrubs that are too large for hand-pulling, and it disturbs less soil. Another example is kudzu. The root crown can usually be dug up, but if that root is under a large tree root, you would disturb the tree too much if you try to dig it out. Japanese chaff flower is also a very high priority to remove. While we usually dig up the roots and remove the entire plant (do not leave it to mulch, as it will re-grow), if it has been spreading for several years, this is very labor intensive. We simply cannot allow it to go to seed, and so to get it under control, we are using herbicide in a few places. Like with question 1, it is about trade-offs. In some cases, we use a little herbicide now so that we can make progress in restoring and maintaining this space.

    Photo on right is pretty, but unfortunately invasive Fortune's Holly-fern

    Phase 2 February 2024 - December 2024

    1. Volunteer days February to May focused on the area near the Beltline, removing English ivy, wintercreeper, oriental bittersweet, various escaped landscaping plants, privet, carolina cherrylaurel, and Amur honeysuckle.
    2. In May we removed kudzu and Japanese hops that are growing near the bridge. 
    3. Summer focus was Japanese chaff flower, and marking out a nature trail.
    4. Fall was round 2 of removal of vines and cherrylaurel.
    5. 1 year anniversary celebration took place in November.

    NOTES:   Click here for photo summary

      

    Kathryn provided history of why this land is still old growth forest. Atlanta’s densification occurred later than many cities, with a major reason being the lack of air conditioning until the 1960’s. A/C and automobiles allowed the densification of Atlanta. The terrain also contributed, with remaining undeveloped areas often being in low lying areas and along steep hillsides. 


    We saw several old growth soil indicator species, including blood root and Persicaria virginiana (also called jumpseed, Virginia knotweed or woodland knotweed.)


    We talked about choices. While it would be nice to some day have only native species, we should modulate the removal and ensure that good plants replace the areas that have been cleared. Letting in more sunlight means that some of the invasives will just grow that much faster. At the entrance, there is a stand of elderberries near a small boxelder maple (also called ash-leaf maple) and a small mulberry. It would make sense to prioritize the elderberry over the boxelder and mulberry. Boxelder is prolific and the mulberry is a hybrid. [These have now been removed.]


    • We saw quite a few mulberries, some are native, some are hybrids. The non-natives are a low priority for removal. The ones with shiny leaves are a hybrid.
    • Invasive cherry laurel can be identified by the smell of the crushed leaves, with the aroma being of maraschino cherries rather than herbal.
    • It is debated whether giant ragweed is native or introduced. If we want to replace it, good candidates are goldenrod and asters.
    • Sweet shrub would grow well in the part shade near the bridge.
    • Silverbell and spicebush would grow well close to the creek.
    • Ragwort and mayapple grow well in the flood plain.
    • Elderberry and river cane would grow well on the north side of the bridge.
