Wedand Revegetation Monitoring Report
July 2003
1.0 Introduction
This report documents the fiffh year of monitoring at Froggr Bottoms. San Juqn Retention Basin
as required by the Wetland Revegetation, Monitoring and ldaintenance Plan- (April 1998).
Annual monitoring will continue thorough 20M to determine whether performance standards are
met from the original plan. A revegetation project is successfirl when after 3 years (2002). the
areas designed for dense revegetation have 85% ground cover with less then I5Yo of that cover
comprised of weed species. Survivorship of tree and shrub species is expected to be 807o or
grear€r. Monitoring was conducted on July 7-2003.
f.i froiect Historf )
In 1997 the City of Port Townsend constnrcted a stormwafer retention pond from a highly
degraded Cuegory Itr wetland. Drning the San Juan Street Improveme,lrt Projea additional
stormwater from San Juan Avenue was directed towards Froggr Bottoms basin. In addition-
street runofffrom Cedar Street and Pacific Avenue now pass through bio-filtration swales before
entering the basin.
1.1.1 Voluntecrs
Through extensive volunteer effort (over 600 hours) during 1998 and 1999 the site hes been re-
vegetated with over 200 trees- 400 shnrbs. and 500 emergent/herbaceous natives. In addition to
diversiffing plant species. woody debris was added to the site. Volunteers planted an additional
200 small trees and shrubs in March 2002. No maintenance or irrigation followed these
plantings so strrvival rates were low. although many of the small pines and firs are vigorous and
healthy.
1.1.2 Maintenance and lrrigetion
Maintenance of the plana at Froggr Bottoms has beeu sporadic. originally conducted only by a
volunteer goup. The site was too large and the weed population too great for even the most
energetic volunteer goup. A large portion of the species did not survive past the first or second
year. An irrigation system wittr auomatic timers was installed in 1998 but was not activat€d
during the driest parts of the srunmer and the above ground pipe was damaged frequently.
Species mortality was also due to compacted soils. deer grazrng, vandalism, and the dominance
of weedy species. Annr-ral weedirg and mowing is now part of the maintenance progmm and site

conditions are greatly improved. The City sheet crews, in conjunction with Resource Renewal.
Inc. Quilcene, WA (an independent contractor) have reduced the weed cover. A chronolory of
plantings and maintenance is included in the Appendix (Figure VII).
1.1.3 Hydrologr
The hydrolory has fluctuated greatly since the consffuc'tion ofthe San Juan Retention Basin.
During the monitoring period in 1998 water filled the majority of the low lying areas of the
retention basin. In 2001 no wat€r was presenl soils were cracked, established wetland dependant
vegetation was stresse4 and weedy species were spreading. Many well established shrubs
including red-osier dogwoods died during this drought. Ponded water was present once again
during the 2002 monitoring season btrt evaporated in August. During this monitoring phase there
was no standing water in the pond but surface saturation was present and the wetland plant
community 4ppea$ healthy.
2.0 Methodolory
2.1 Project Goals and Objectives
One of the primary goals of the Frogry Bottoms Revegetation Project is to use native plants to
create a diverse habitar which over time will encourage additional use by wildlife. Native
vegeration was selecte4 gving priority to species ttrat benefit wildlife and can withstand local
climatic conditions. Long-range goals include enhancing open space and utilizing biofiltration as
a creative solution to stormwater problems.
Goals from ttre original plan ttrat have been met in 2003:
1. Several species of trees and shrubs are established. diversiffing the structural layers of the
site.
2. The diversity of species creates additional food sources and nesting and perching sites for
wildlife.
3. The site is used by ntrmerous bir4 mammat, and amphibian species (deer observed
gl:azlrrgand bedding, rulny species of birds. chorus frogs).
4. Open space is preserved near Blue Heron Middle School and is used by the
neighborhood. A number of informal foot and bicycle trails traverse the site. especially
around the perimeter of the pond.
5. The site retains seasonal stormwater. which is filtered through the emergent vegetation
growing in the pond.
The project has been implemented using a phased installation process as indicated in the
maintenance and monitoring schedule ofilined in Table 1.

2.2 lvlonitoring Methods
The site was divided into 5 zones; water meters. the staffgauge, and other permanent landmerks
define Zone boundaries. A map of the location of the monitoring Zones is included in the
(Figrne I). Same species were generally grouped in specific zones according to habitat
requirements.
2.2.1 Determining survival Rates of Trees, Shrubs, and Emergen8
Monitoring data sheets were used to determine plant suwivorship and to record conditions of
planted trees. shrubs. and emergents. These data sheets are included in the Appendix (Figures tr.
Itr, and tV). The indiviftial plants were counted throughou the entire site and compared with the
numbers originally planted. More plants were counted this year than in previous years since the
site has been mowed. Smalt plants that previously were under a weed cover are more mature and
visible and all tree and shrubs are now significant in size.
The majority of emergents were planted in or near the pond. Populations of volunteer native
rushes. bulrushes. and sedges that have adapted to the site are also monitored.
2.2.2 Documenting Wetland Changes with Photographs
Photographic monitoring provides a visual record of the restoration effort and is an excellent way
to qualitatively document plant community changes over time. Six permanent photopoints were

3.0 Results and Discussion
Dixie Llewellin of Olynnpic Wetland Resources" Inc has been retained to collect data for this
monitoring project. Fieldwork was conducted on July 7. 2003.
Vegetation was planted and maintained from 1997 through 1999 by volunteers. Maintenance
ys35 minimal in 2000 and 2001. Mowing and weeding during 2002 and 2003 has improved
species survival, weed suppression" and aesthetics. Weedy species are no longer the dominant
cover along Cedar Street or San Juan Avenue. In areas of Froggy Bottoms where native soils
were not disnrrbed" mowing has not been necessary since undesirable weed cover is minimal and
the planted species are thriving.
3.1 Surrdvorship of Planted Species
Survival rates were calculated by comparing live plants counted during the 2003 survey to the
total numbers planted. Monitoring forms for each of the plant communities are included in the
Appendix (Figures I m and IV).
3.1.1 Forest Sunival
The survivalrate for trees is greater than the number originally planted (Il9%)- This figure
includes the extra trees planted in 2002. Along the pond's perimeter. Pacific willows are
numerous and are forming a hedge 5 to 6 feet tall. Hookers willows. planted as live stakes. are
forming a thick shrub layer as well. Near the interpretive sign and along Pacific Avenue. the
Garry oak appear geen and have healthy new growth. The regular weeding program has v3glv
improved their chance of survival. At one point many of the trees were buried in Himalayan
blackberries.
Several species ofdeciduous trees are stressed and dying due to drought and poor soil conditions.
These include mountain asll big-leaf maple. vine maple. and serviceberry. The cottonwood- ash.
hawthorn" oah and aspen are well established and thriving.
Evergreen species in general are adapting well to the site: Douglas firs and shore pine are robust
and have new growth. Unfortunately the spnrce appears to be suffering from the spruce aphid: 3
of the original 10 trees have not survived.
3.1.2 Scrub/Shrub Surwival
The survival rate is low for shrubs (33%) when comparing the number present in 2003 to the
number planted in 1998 and 1999. The percentage of shrubs surviving the original installation in
1999 was low. Several hundred shrubs did not survive since they were planted in locations
where heavy clay soils were mounded from the excavation of ttre retention basin. Competition
Olympic Wetland Resources- Inc. 4
gs1 Jrren Rerention Basin Wetland Revegetation Monitoring Repon

from weeds and lack of water also prevented the establisbment of numerous plants. Therefore-
the number of shrubs surviving past the first year after installation was compared with this years
count. There is an86oh survival rate of shrubs when comparing 2000 with 2003. Shrubs that are
sgrviving now can withstand our dry srunmers. Ninebark and ocean spray are robust and healthy
and native populations of snowberry are spreading. The shrubs layer is most vigorous in areas of
native undisturbed soils.
3.13 Emergent Survival
ln the low-lying basin the emergent wetland dependant vegetation is healthy. recovering from the
drought in 2001. Survival rate is high and populations of emergent species are spreading. The
dgminant cover consists of both planted and volunteer native species. Over 85% of the plant
cover consists ofdesirable native species.
3.1.4 Interpretive Area
Populations of poison hemloch Canadian and bull ttristle. and curly dock have dominated the
interpretive area- accessed via a gravel trail from Pacific Avenue. During the monitoring project
the site was mowed and the few remaining planted species are the Gan], oak. We recommend
that this interpretive area be re-evaluated and improved since it is a public access to the site.
3.2 Action Items

private contractor (Resource Renewal)
1. SanJuanAvenue
2. lnterpretive area
3. Cedar Street
Remove all reed canarygrass and Scot's broom. blackberries
Mow along fence line south of pond to control emerging population of blackberries
3.2.f We€dy Species
Weed invasion has been a major problem. Weeds have hindered the growth and smothered many
of the planted species. The current maintenance program of annual weeding and mowing is
effective. Scot's broom is no longer present on site and the majority of poison hemlock and
thistle have been mowed.
A potential problem of encroaching blackberries w:ls observed along the fence line south of the
basin. This area will need to be included in the weeding progrcm next year.
4.0 Summary
Performance standards established in the Froggy Bottoms. San Juan Retention Basin Wetland
Revegetation. Monitoring, and Maintenance Plan. April 1998 require that the site be dominated
by a cover of 85o/o ''desirable species" with less than 15% weed species and ttrat survivorship of
tree and shrub species is 80% or gleater 5 years after final planting (2004).
Ollmpic Wetland Resources. lnc. 5
San Juan Raention Basin Wetland Revegetation Monitoring Repon
jull 2003
The planted areas within Frogry Bottoms are diverse. with a variety of soil types and site
conditions. In most locations performance standards are meL The ongoing annual maintenance
has vastly reduced the dominance of weed cover in the problem areas. Originally 197 trees. 41i
shrubs. and several hundred emergent species were planted. Mortality due to lack of
maintenance. poor soils, lack of water, and inappropriate plant choices has reduced the numbers
over time. However. ttre majority of the plants that survived the first year after installation are
thriving and spreading. Native species. both planted and volunteer. are the dominant cover in the
emergent zone.
Monitoring for 2003 reveals a high success rate for trees. with over 1007o survival rate. This rate
is due to spreading population and extra trees added n2002. The survival rate for shrubs is low.
33% when comparing numbers from plants originally planted. The survival rate is 86% when
evaluating survival of shrubs surviving two years after installation (comparing survival in 2000
vs. 2003. There was an especially high mortallty rate in shrubs after the initial planting but the
surviving population is well established and healthy. The survival rate for emergent species is
excellent over 100% due to spreading populations. Standing water was present in the pond until
June this year: wetland dependent vegetation was healthy.
The regular maintenance consisting of annual mowing and weeding has vastly improved
conditions for the planted species and the overall aesthetics at Froggl Bottoms. Many of the
original project goals have been met. Over 25 different species of native trees. shrubs. and herbs
introduced are now thriving and spreading. This site was originally a waste area with only
grasses. These plants have increased available food sources and nesting areas for birds-
mammals. and amphibians. The pond effectively retains and filters stormwater during ttre wet
seasons while the rushes. sedges, and bulrushes actively filter stormwater. The open space is
utilized by nearby schools and surrounding neighborhoods.
The fi.rture goals for Frogry Bottoms should be evaluated to dovetail the site with other long-
range City projects. Topics to be considered include improving the interpretive area with
additional plantings and connecting the site to existing public trails system. I would be happy to
meet with City staffto discuss the firture improvements for this restoration project.
