Scope of Intrusion. Regular biological community disturbed by outlandish obtrusive species Open rangeland Forested environments Marshes, wetlands Amphibian circumstances (lakes/lakes, streams, watering system trenches). Why an Issue?. Colorful species are very adjusted to different environmental territories
Transcripts
Slide 2

Range of Invasion Natural biological community disturbed by fascinating intrusive species Open rangeland Forested environments Swamps, wetlands Aquatic circumstances (lakes/lakes, streams, watering system waterways)

Slide 3

Why an Issue? Extraordinary species are exceptionally adjusted to differing environmental zones High conceptive limit No common foes (sickness, creepy crawlies, and so on.) Biological desert

Slide 4

Management Primary technique is PREVENTION!! Intrusive appraisal, expectation models Mechanical Effective however not down to earth on expansive regions Generally does not kill Also incorporates smolder, surge, cutting, and so forth. Natural control is IDEAL, but…………. Compound – the huge issue is………..?

Slide 5

Selectivity In products you are attempting to control all species with the exception of the harvest In obtrusive plant control you are attempting to control one animal groups and not damage everything else Integrated methodology is the key, yet a noteworthy choice must be made first

Slide 6

To Eradicate or not to Eradicate Eradication high level of coordination & observing high $$, isolates wipe out all people, propagules, and so on that could recover a populace persistently screen to guarantee annihilation Maintenance control is that circumstance where you always screen the populaces and control when levels achieve a sure edge, which is for the most part low

Slide 7

Caulerpa $ 4 million 5 years

Slide 8

Nascent Foci Approach Start on the remote populaces first and work into the inside Accurate review of infestation and information on the scope of spread (instrument of dispersal) Continually screen over the region officially secured

Slide 9

Revegetation Planting back an attractive animal groups that will give environmental strength and potentially prevent/square reinfestation of intrusive species When and what amount obtrusive control do you require? Plausibility of particular control?

Slide 10

Response to Imazapyr

Slide 12

Impacts Category 1 obtrusive species (FLEPPC) Ability to spread into undisturbed locales Extremely quick development > 8 inches/day Smothers trees and local understory species Spreads quickly through huge creation of bulbils

Slide 13

Mature Plant Rapidly climbing, twining herbaceous vine Vines killed by ice Regrowth from underground tubers

Slide 14

Leaves and Flowers Leaves cordate All leaf veins emerge from leaf base Flowers are unnoticeable, emerge from panicles from leaf axils

Slide 15

Bulbils Aerial tubers, borne in leaf axils Generally roundish, smooth and dark to cocoa in shading Primary method for spread

Slide 16

Preventative Limit planting as an elaborate Remove existing plants, including resprouts and before bulbils are delivered Avoid spread through debased garbage, brush or soil Clean trimmers and other brush-cutting hardware

Slide 17

Cultural Programs to teach mortgage holders about the issues connected with air potato and fitting distinguishing proof Remove populaces along conduits Bulbils will buoy to new regions Gather bulbils in fall after ice (Gainesville Air Potato Roundup)

Slide 18

Biological There are no known natural control specialists accessible for air potato administration in Florida or the southeastern U.S.

Slide 19

Mechanical Hand pull youthful seedlings, including all roots, uncover tubers Mowing is successful, however must be rehashed and may spread bulbils Burning is not a suitable choice – flame steps into shade of trees

Slide 20

Chemical Over-the-top applications before bulbil development, amid spring and summer Thoroughly wet leaves with herbicide Triclopyr – 2% arrangement Glyphosate – 2 to 3% arrangement Use surfactant at 0.25% Retreatment important to slaughter tuber and resprouting bulbils

Slide 22

Biology Also known as silk tree Medium-sized tree, 20 - 40 feet tall Legume plant - fit for settling nitrogen Introduced from China to the U.S. in the mid 1700’s

Slide 23

Mature Plant Small tree – 20 to 40 feet in tallness Highly fanned, meandering propensity Leaves and blossoms in bunches toward the end of branches

Slide 24

Mechanical Hand pull youthful seedlings, including all roots, rehashed pulling for resprouts Cut tree down at ground level Girdling is powerful for expansive trees Cut through bark more or less 6 inches over the ground, encompassing tree base Mowing is successful on little saplings and resprouts, however must be rehashed

Slide 25

Chemical - Foliar Over-the-top applications for seedlings, resprouts and little trees Thoroughly wet leaves with herbicide Triclopyr – 2% arrangement Glyphosate – 2% arrangement Clopyralid - 0.2 to 0.4% arrangement Use surfactant best case scenario results connected July to October

Slide 26

Chemical - Basal Individual trees, close attractive species Use 25% triclopyr arrangement with basal oil Apply 12 to 15 inches over the ground on tree trunk Wet completely for good control, splash until keep running off is detectable at ground line

Slide 27

Chemical – Cut Stump Individual trees, close alluring species Cut trunks/stems horizonally at or close ground level Apply 25% arrangement of glyphosate or triclopyr Cover the external 20% of the stump Marker (blue) color is useful

Slide 28

Putting It All Together Control methods regularly not known or accessible A general guideline - glyphosate for most species, triclopyr for broadleaf species and vines Treat ‘pockets’ of intrusive species – confined; yet make sure not to spread the species in the process Target zones along streams and riverbeds, as those zones give more noteworthy ability to spread

Slide 29

Spring Focus first on yearly species Controlled viably as seedling plants Retreatment may be important in the late spring Final check in the late summer/early tumble to slaughter remaining plants that may set seed Follow-up the following year or two The key with yearly species is counteractive action of seed set.

Slide 30

Late Summer/Fall Perennial species with vegetatively tireless structures, fall medicines are by and large best Herbicides translocated to the vegetative propagules and give longer, more reliable control If species blossom in the fall, make certain to treat before seed set

Slide 31

Winter Target trees amid the winter months, particularly basal bark medications Allows adequate time to check later in the mid year/early succumb to regrowth Cut stump medications can be performed at whatever time so utilize the time amid the cooler winter months for this action

Slide 32

Bringing It Together Set up a lattice with different treatment zones, refering to issue species in every zone GPS referencing is especially useful Follow-up will be basic, however you ought to in the long run get to a point where routine upkeep will be all that is essential.

Slide 35

Impacts Category I obtrusive species (FLEPPC) Disrupts common plant groups Shade out alluring species, particularly local seedlings and understory plants Resprouts promptly after flame or mechanical evacuation Heavy natural product set following 2 years of foundation

Slide 36

Mature Plant Small upright bush, up to 6 feet tall Often develops in huge provinces Shade tolerant, understory species

Slide 37

Seedlings regularly discovered enclosing an experienced plant Plants will stay in adolescent stage until adult example is uprooted

Slide 38

Leaves Alternate course of action, however tight to the primary stem Scalloped edges Dark, thick, lustrous green

Slide 39

Flowers and Fruit Flowering happens in spring – little white/pink bunches Fruit are splendid red and swing from the plant Persist on the plants for a while

Slide 40

Fruit and Seed Fruit promptly devoured by untamed life - winged animals Seed practicality is high and grow in an extensive variety of soil conditions

Slide 41

Mechanical Hand pull youthful seedlings, including all roots, rehashed pulling for resprouts Mowing or section/slashing is viable, yet must be rehashed because of resprouting from rootstocks. On the other hand, cutting may not be useful in numerous ranges.

Slide 42

Chemical - Foliar Over-the-top applications for seedlings and expansive plants Thoroughly wet leaves with herbicide Glyphosate – 2-3% arrangement in addition to surfactant at 0.25% to expand herbicide infiltration of the waxy leaves 2,4-D – 2-3% arrangement is additionally powerful, however just on seedlings or resprouts

Slide 43

Chemical - Foliar Over-the-top applications for seedlings and huge plants Use 18% triclopyr arrangement with basal oil or 10% diesel fuel

Slide 44

Impacts Category II obtrusive species (FLEPPC) Limited spread into undisturbed locales Strong contender Readily builds up, high amount of seed or resprouting Fixes nitrogen Competes adequately for daylight and supplements

Slide 45

Stems and Bark Younger stems lime green, secured with lenticels (little pits in bark) On more established stems turns out to be light chestnut to grayish Smooth bark

Slide 46

Leaves Alternately orchestrated Bipinnate compound 6 to 20 creeps in length 20 to 60 handouts for each branch Leaf course of action gives mimosa greenery like or fluffy appearance

Slide 47

Flowers Flowering happens from May to July Borne in terminal groups at base of the ebb and flow year’s twigs Fragrant, pink in shading, bunched up

Slide 48

Fruit and Seed Flat seed pods, straw-hued, 6 crawls in length Pod contains 5 to 10 seeds, light cocoa oval-formed Seed pods persevere on the tree all through winter

Slide 49

Seed Scarification needed for germination Seed torpidity for a long time Dispersal happens through water and may happen thr
