Abstract:

Plant phenology or life-history pattern, changes seasonally as plants

grow, mature, flower, and produce fruit and seeds. Plant phenology

follows seasonal patterns, yet annual variation may occur due to

annual differences in the timing of rainfall and ambient temperature

shifts. Plant foliage growth and fruit and seed production are

important aspects of plant population dynamics and food resource

availability to animals that feed on plants, fruit, and seeds. The

purpose of this study is to assess plant phenology patterns across a

series of biotic communities that represent an environmental moisture

gradient. These communites include: Chihuhuan Desert creosotebush

shrubland, Chihuahuan Desert black grama grassland, Chihuahan

Desert/Great Plains/Rocky Mountain juniper savanna, and Rocky Mountain

pinyon pine/juniper woodland. Plant phenology is recorded for all

plant species across 5 replicate 200 m transects at each of the 4

habitat sites. Plant phenology measurements are taken once every month

throughout each year. The first 10 individuals of each plant species

encountered along each transect are assessed for life-history

status. Data recorded include the status of leaves, flowers and

fruit. Leaves are recorded as new, old, brown or absent, flowers and fruit are

recorded as present or absent. Plant phenology data were collected in all 4 core research sites

sites in 2000.

This is part of a multi-part data set.

Collecting the dataEach transect is located and sampled by one technician. Measurementsare started from the northern (stake #12) endof a transect. The technician walks in a straight line from one stake tothe next surveying the area that is approximately 1 m on each sideof this line until the opposite end of the transect is reached. As atransect is walked, phenological conditions are recorded for eachspecies that occurs along the transect. The phenological condition ofthe first 10 individuals of each species is recorded. After theconditions of ten individuals have been recorded no more observationsare made for that particular species even though more may beencountered. Conversely, for rare species only a few individuals maybe encountered so there will be less than 10 observations recorded forthat particular species.Because measurements are taken on separate individuals, it isimportant to note that many plants have clonal growth forms. This canbe seen in some grasses that occur as a clump of overlappingvegetation. In this case each clump is treated as a singleindividual. This is also true for some cactus and yucca species thatappear as a cluster of many individual heads.

Recording the dataFor each transect, the following is recorded:1. Recorder- Recorder's name and also the name(s) of anyonehelping take measurements on that particular transect.2. The date (month, day, year)3. The site (P, J, G, C) whereP = Cerro MontosaJ = SavannaC = Five-Points creosoteG = Five-Points grassland4. The web (1,2,3,4,5)The species code for all the species occurring along the transect isrecorded. Then the phenological conditions of the individual plantsin the area are recorded in the Fol and Flw columns of the data sheet.The Fol column is for status codes reflecting the condition of a plant'sfoliage and the Flw column is for codes reflecting the reproductivestatus of the plant. The status codes are as follows:Foliage codes Reproductive codesN = new green foliage FL = New FlowersO = old green foliage only FR = New FruitsB = brown leaves only FF = Fruits and FlowersZ = no leaves Z = No Fruits or Flowers

Determining Phenological Conditions* Foliage Conditions1. New green foliage (N) This category refers to aplant that is producing new vegetative tissue. The production of newvegetative tissue can be characterized in several ways depending onthe species. In many herbaceous plants, new vegetative growth will beindicated by the presence of immature leaves or stems. In general, inherbaceous plants look for this growth near the tips of shoots andalso at axillary buds.New growth is delineated by the presence of immature scales injunipers and immature needles in pines.For species that have a rosette growth form, seen in yucca and someherbaceous plants, the center of the rosette is examined for thepresence of immature leaves.In cacti, the spines are modified leaves and do not readily indicatenew vegetative growth so cacti are examined for production of newstems. For example, in Opuntia spp., the presence of a new stem/padrepresents new green foliage as each stem-joint represents a season'sgrowth. Cacti that exhibit a cylindrical growth form are more difficult toclassify. Cacti with tuberculate stems are examined for newtubercules. These can often be seen in the center of the head.Mammilaria spp. are good examples of cacti with tuberculate growth.More problematic are the ribbed cacti where the growth of one seasonis continuous with that of the preceding season. While these speciesmay be producing new growth it is extremely difficult to identify andthus they are usually categorized as old green foliage.2. Old green foliage (O) This category refers to a plant that is notproducing new vegetative tissue but exhibits only mature greenfoliage.3. Brown leaves (B) This category refers to a plant that has onlybrown leaves and is used to indicate a period of senescence ordecline.4. No leaves (Z) This category is similar to the above category. Itis meant to capture a period of senescence or decline and refers to aplant that has subsequently dropped its leaves. It appliesto only some growth forms, those that drop their leaves during aperiod of dormancy or senescence. This category is not used forplants that normally do not have leaves such as Ephedra spp.* Reproductive Conditions1. New flowers (FL) This category refers to the presence of flowersat anthesis (open flowers). For many species the petals are large andshowy making this condition easy to identify. In species with small orreduced flowers, this condition represents the presence of keyreproductive structures such as stamens and/or carpels.2. New fruit (FR) This category refers to the presence of a ripenedovary that contains seed. Open fruits that do not contain seed arenot categorized as fruiting. Open fruits that do contain seed belongin this category.3. Fruits and Flowers (FF)This category indicates that both fruit and flowers are present.4. No Fruits or Flowers (Z)This category indicates that neither fruits or flowers are present.
