Iowa Natural Resources, Agency Performance Plan, FY2013

The work of the Department of Natural Resources impacts the lives of all Iowans. Iowans deserve a clean environment and quality natural areas for public use and enjoyment. This report reflects the progress made during fiscal year 2013 (FY13) toward our goals and provides information regarding the condition of our state’s natural resources and the effectiveness of our programs. In FY13, we continued to improve collaboration with other executive branch agencies. The DNR and DOT work very closely on the issuance of permits needed for road and bridge constructions, but recently we have also been working together to meet the administrative needs of the agencies. The DNR is working closely with the DOT to adopt an Electronic Records Management System used by the DOT. This system will improve accessibility to public documents and reduce the amount of paper files retained in storage. The DNR also continues to improve collaboration with other agencies, such as the Iowa Economic Development Authority as we work closely with them on business development in the state. The DNR strives to continually improve our customer service and how we can meet Iowan’s needs. As an example, the online reservation system for campground reservations has grown over the past eight years so that now 88% of the camping reservations are made online. The DNR continues to improve our online presence and accessibility. In FY13 the Iowa Legislature approved paying off the State’s bond debt used to construct Honey Creek Resort State Park. By removing this debt, the DNR will be able to focus more on the future of the Resort, rather than the past debt. Finally, in August of 2012, the DNR was faced with a tragic accident, where a seasonal parks employee died after rolling a mower into a lake. This incident has caused us to establish a Safety Program at the DNR and to review all of our departmental safety trainings, programs, and equipment. By focusing on our employee’s safety and well being, it is another way that we can demonstrate that at the DNR, our employees are our greatest asset.

05040-015 Viking Lake Watershed Final Report

Viking Lake State Park is beautiful resource which has been special to residents of Southwest Iowa and visitors from around the region. Unfortunately, Viking Lake itself is being impacted by non-point source pollution. Water quality conditions are becoming the reason that visitors are shying away from the park instead of flocking to it. To combat these non-point source problems the Viking Lake Water Quality Project has been initiated and $327,000 has been allocated through the Section 319/WSPF Program which will address water quality concerns in the watershed. Additionally, IDNR Fisheries is preparing for an entire renovation of Viking Lake in 2006. One funding gap remains, that may prevent this comprehensive water quality project from achieving a successful endpoint. Funds are still needed for the renovation of malfunctioning septic systems at Viking Village housing development which is adjacent to the park, and has been identified as a primary source of contamination entering the lake. The intent of this application is to secure funds so that these septic system problems can be corrected and water quality conditions of this important natural resource restored for public enjoyment.

07032-012 Lake MacBride Watershed Final Report

Lake Macbride is considered to be one of the top four lakes for fishing in the state of Iowa. It is widely used by the public and contributes significant economic benefits to the county. Lake Macbride is situated in the North Corridor which is one of the fastest growing areas in the state. The lake has a surface area of 940 acres and drains 16,205 acres. Lake Macbride is on the Iowa 303(d) list for excessive sediments and nutrients. In 2001, Lake Macbride State Park received over 2.5 million dollars from the Marine Fuel Tax and Fish and Wildlife Trust to install 2 silt basins and stabilize over 12 miles of shoreline in the lake. Also in 2001, the Johnson County SWCD received a WSPF allocation from DSC to address agriculture and urban runoff issues in the watershed. Section 319 funding was received in 2002 to continue watershed efforts to the present. A watershed assessment was completed in 2003 to guide watershed activities. In 2005, a TMDL was completed for the lake. Since 2001, over $645,000 dollars has been spent by landowners and funding partners to install conservation practices in the watershed. Watershed efforts have resulted in the reduction of over 4200 tons of soils from being delivered into Lake Macbride. Nutrient reductions have also occurred from the development of nutrient management plans on 2000 acres. The District is in the process of wrapping up watershed efforts on private land. A series of 13 structures is planned to be installed in the State Park over the next several years. One of the last remaining items that still needs addressed is 1,400 feet of eroding shoreline adjacent to Lake Macbride along Cottage Reserve Road. The road is under the jurisdiction of the Johnson County Board of Supervisors. Both the Board of Supervisors and the IDNR are willing to contribute substantial dollars to address the 250 tons of soil that are being directly delivered to Lake Macbride each year.

Anatomia foliar das espécies de Pteridaceae do Parque Estadual do Rio Doce (PERD) - MG

O objetivo desse estudo foi selecionar caracteres que possam auxiliar na taxonomia das espécies de Pteridaceae ocorrentes no PERD. Durante levantamento preliminar realizado no PERD, foram coletadas 15 famílias, 27 gêneros e 57 espécies de Pteridophyta. A família que apresentou maior número de representantes foi Pteridaceae com 17 espécies, distribuídas em quatro gêneros (Adiantum, Hemionitis, Pityrogramma e Pteris). As folhas destas espécies apresentam pecíolo glabro, piloso ou escamoso cuja epiderme é uniestratificada, córtex constituído por esclerênquima e parênquima e o sistema vascular representado por um meristelo, em Pteris e Hemionitis, e dois ou três meristelos em Adiantum e Pityrogramma. Na região distal do pecíolo, esses meristelos são classificados como do tipo "Onoclea" e "Asterochlaena" em Adiantum, "Grammitis" em Hemionitis, "Onoclea" em Pityrogramma e "Loxsoma" e "Pteris podophylla" em Pteris. A lâmina foliar apresenta epiderme uniestratificada com idioblastos esclerenquimáticos paralelos, oblíquos ou restritos às nervuras, em Adiantum e Pityrogramma e reforçando as margens, em Pteris; os idioblastos estão ausentes em Hemionitis. Algumas espécies apresentam a lâmina foliar pilosa ou escamosa. Os estômatos ocorrem na face abaxial das pínulas sendo anomocíticos, às vezes associados a diacíticos, em Adiantum, Hemionitis e Pityrogramma e polocíticos, associados a copolocíticos, em Pteris. O mesofilo homogêneo é constituído por células braciformes, na maioria das espécies de Adiantum, ou por células lobadas, tendendo a isodiamétricas, nos demais gêneros. Os caracteres anatômicos mais relevantes para a identificação das Pteridaceae do PERD foram: presença de pêlos ou escamas; tipos de estômatos; presença e distribuição de idioblastos na epiderme e tipo e disposição do(s) feixe(s) vascular(es) no pecíolo.

Atlantic Forest succession over calcareous soil, Parque Estadual Turístico do Alto Ribeira - PETAR, SP

The forest succession after abandonment of slash-and-burn agriculture over calcareous soil in Brazilian Atlantic Forest was assessed. This is one of the world's most threatened Biome, with only 8% remaining. The study area is located over calcareous soil inside the Alto Ribeira Touristic State Park (PETAR), southeast Brazil. The phytossociological survey showed a successional pattern dominated by species of Leguminosae, especially Piptadenia gonoacantha (Mart.) J.F. Macbr. This species occurs in calcareous soils as a substitute of Tibouchina pulchra (Cham.) Cogn. (Melastomataceae) that is the most usual dominant tree species in early succession over acidic soil, which is the most common situation in this Biome. These results are important for a better understanding of Neotropical forest biodiversity and characterize a unique genetic bank in this highly endangered Biome. They are also decisive to support actions regarding rehabilitation of degraded lands and a potential tool for Neotropical forest sustainable management, both inside and around the conservation unit.

Horizontal and vertical tree community structure in a lowland atlantic rain forest, southeastern Brazil

The horizontal and vertical tree community structure in a lowland Atlantic Rain Forest was investigated through a phytosociological survey in two 0.99 ha plots in the Intervales State Park, São Paulo State. All trees > 5 cm diameter at breast height were recorded. 3,078 individuals belonging to 172 species were identified and recorded. The Shannon diversity index was H' = 3.85 nat.ind.-1. The Myrtaceae family showed the greatest floristic richness (38 species) and the highest density (745 individuals) in the stand. Euterpe edulis Mart. had the highest importance value (33.98%) accounting for 21.8% of all individuals recorded. The quantitative similarity index was higher than the qualitative index, showing little structural variation between plots. However, the large number of uncommon species resulted in pronounced floristic differences. A detrended correspondence analysis (DCA) generated three arbitrary vertical strata. Stratum A (> 26 m), where Sloanea guianensis (Aubl.) Benth. and Virola bicuhyba (Schott. ex A.DC.) Warb. were predominant showed the lowest density. Stratum B (8 m < h < 26 m) had the greatest richness and diversity, and stratum C (< 8 m) showed the highest density. Euterpe edulis, Guapira opposita (Vell.) Reitz, Garcinia gardneriana (Planch. & Triana) Zappi, and Eugenia mosenii (Kausel) Sobral were abundant in strata B and C. The occurrence of strata in tropical forests is discussed and we recommend the use of DCA for others studies of the vertical distribution of tropical forest tree communities.

Aquatic Hyphomycetes in the Parque Estadual das Fontes do Ipiranga - PEFI, São Paulo, Brazil

In the State Park Parque Estadual das Fontes do Ipiranga - PEFI, located in the city of São Paulo, samples of submerged mixed leaf litter were collected monthly from 10 sites with different levels of eutrophication, from October 2003 to April 2005. Some abiotic factors, such as pH, temperature, conductivity and dissolved oxygen were simultaneously measured in 20 cm deep water at each site. The leaf litter samples were washed in laboratory, cut into 1 cm² pieces and incubated in Petri dishes containing distilled sterile water for five to seven days at 15 °C to 20 °C. Twenty-four aquatic Hyphomycete species were identified, with predominance of Anguillospora crassa Ingold, Lunulospora curvula Ingold, Tetrachaetum elegans Ingold and Camposporium pellucidum (Grove) Hughes. First reports for South America are: Anguillospora filiformis Greathead, Dendrospora erecta Ingold and Pyramidospora casuarinae Nilsson. These species, as well as Tetracladium setigerum (Grove) Ingold, Tricladium splendens Ingold and Varicosporium elodeae Kegel, are reported for the first time in Brazil. According to the multivariate analysis, the occurrence of the aquatic Hyphomycetes was mainly influenced by the trophic level of the aquatic environments.

Multiple dormancy and maternal effect on Miconia ferruginata (Melastomataceae) seed germination, Serra de Caldas Novas, Goiás, Brazil

Species with mostly asexual reproduction are interesting subjects for germination studies since variation would be more easily linked to environmental factors. Miconia ferruginata DC. is an apomictic treelet in Brazilian cerrado areas on rocky outcrops. Germination of seeds collected from individuals occurring in the Serra de Caldas Novas State Park, Goiás, was studied in three experiments under controlled conditions. Germination characteristics differed among individuals and were correlated with altitude and soil Al content. Seeds from plants growing at lower altitudes, with lower soil aluminium content, presented malformed seeds with absence of embryo which rendered lower, but better synchronized germination. The nested analysis showed that from the total variance, 78.14% for germinability, 54.56% for uncertainty of the germination process, and 68.30% for the quantity of seeds without embryo was attributed to the altitudinal effect. Individuals nested within altitude contributed up to 16.93% for the total variance. It means that there is low variability among individuals of the same altitude and high variability among individuals from different points of the slope, making clear that for the studied population the environmental effect is stronger than the genetic component to determine the seed quality. The testa of the seeds provides a mechanical dormancy which seems to be associated also with phenolic compounds, which help to disperse germination through time. Photoblastism was also registered for seeds of this species.

Integrated Nitrogen CAtchment model (INCA) applied to a tropical catchment in the Atlantic Forest, Sao Paulo, Brazil

Stream-water flows and in-stream nitrate and ammonium concentrations in a small (36.7 ha) Atlantic Forest catchment were simulated using the Integrated Nitrogen in CAtchments (INCA) model version 1.9.4. The catchment, at Cunha, is in the Serra do Mar State Park, SE Brazil and is nearly pristine because the nearest major conurbations, Sao Paulo and Rio, are some 450 km distant. However, intensive farming may increase nitrogen (N) deposition and there are growing pressures for urbanisation. The mean-monthly discharges and NO3-N concentration dynamics were simulated adequately for the calibration and validation periods with (simulated) loss rates of 6.55 kg.ha(-1) yr(-1) for NO3-N and 3.85 kg.ha(-1) yr(-1) for NH4-N. To investigate the effects of elevated levels of N deposition in the future, various scenarios for atmospheric deposition were simulated; the highest value corresponded to that in a highly polluted area of Atlantic Forest in Sao Paulo City. It was found that doubling the atmospheric deposition generated a 25% increase in the N leaching rate, while at levels approaching the highly polluted Sao Paulo deposition rate, five times higher than the current rate, leaching increased by 240%, which would create highly eutrophic conditions, detrimental to downstream water quality. The results indicate that the INCA model can be useful for estimating N concentration and fluxes for different atmospheric deposition rates and hydrological conditions.

Bilateral anomaly in the style of Sciopemyia sordellii (Shannon & Del Ponte) (Diptera, Psychodidae)

This paper presents a male specimen of Sciopemyia sordellii with a rare bilateral anomaly, consisting in eight spines in a style and five in the other. This species has four spines in each style as its normal number. The specimen was captured using a CDC light trap, in a forested area in the State Park ""Floresta Estadual Edmundo Navarro de Andrade"", in May 2004, located in the city of Rio Claro, Sao Paulo State, Brazil. Similar anomaly was once described but this is the first specimen found with a bilateral alteration. It may cause confusion in taxonomic identification and even lead to description of new species, increasing the number of synonymies.

Paepalanthus hirtellus, a new species of Paepalanthus subsection Actinocephaloides (Eriocaulaceae) from Minas Gerais, Brazil

In this article we describe and illustrate the new species Paepalanthus hirtellus (Eriocaulaceae, Paepalanthoideae). The species is, as far as known, restricted to Pico do Itambe State Park, in the state of Minas Gerais, Brazil. Paepalanthus hirtellus occurs on the campos rupestres of the Espinhaco Range. We compare it with P. lombensis and P. chrysophorus, the two morphologically most similar species. We provide additional comments on the morphological variability, habitat, geographic distribution and we provide its conservation status.

The occurrence of Laurencia marilzae (Ceramiales, Rhodophyta) in Brazil based on morphological and molecular data

Laurencia marilzae is recorded for the first time from the western Atlantic Ocean; it was found in Laje de Santos Marine State Park, Sao Paulo, southeastern Brazil. The specimens were collected in the rocky subtidal zone from 7 to 15 m depth. The most distinctive characteristic of this species is the presence of corps en cerise in all cells of the thallus, including cortex, medulla, and trichoblasts. The phylogenetic position of the species was inferred by analysis of the chloroplast-encoded rbcL gene sequences from 43 taxa, using two other rhodomelacean taxa and two members of the Ceramiaceae as outgroups. Within the Laurencia assemblage, L. marilzae from Brazil and from the Canary Islands ( type locality) formed a distinctive lineage sister to all other Laurencia species analyzed. Male plants are described for the first time. This study expands the geographical distribution of L. marilzae to the western Atlantic Ocean.

Leishmania spp. in Didelphis albiventris and Micoureus paraguayanus (Didelphimorphia: Didelphidae) of Brazil

Leishmaniasis is kept in nature by the participation of several animal species. This study evaluated the presence of Leishmania spp. in skin samples of free-ranging marsupials Micoureus paraguayanus (n = 95) and Didelphis albiventris (n = 191), captured in Morro do Diabo State Park and in sections of its surrounding forest, in the region of Pontal do Paranapanema, Sao Paulo State, Brazil. The samples were tested for the presence of kDNA of Leishmania spp. by polymerase chain reaction (PCR) and by real time PCR (qPCR). All samples from D. albiventris tested by PCR were negative for the presence of kDNA of Leishmania spp. However, when tested by qPCR, the positivity was 1.6%. A positivity of 7.4% by PCR and 11.6% by qPCR was observed for M. paraguayanus. Sixty-four per cent (9/14) of positive animals were limited to the same forest fragment. Presence of Leishmania (Leishmania) amazonensis and Leishmania (Viannia) braziliensis was detected in M. paraguayanus samples. While D. albiventris is the most studied marsupial species due to its urban habits, other marsupial species such as M. paraguayanus can be potential reservoirs of Leishmania spp. and should also be studied.

An illustrated checklist of Bromeliaceae from Parque Estadual do Rio Preto, Minas Gerais, Brazil, with notes on phytogeography and one new species of Cryptanthus

A checklist of the 14 genera and 34 species of Bromeliaceae from the Parque Estadual do Rio Preto in Sao Goncalo do Rio Preto municipality, Minas Gerais state, southeastern Brazil, is presented. The Tillandsioideae was the most diverse subfamily and was found to be concentrated in rocky field areas. Bromelioideae is also a species rich subfamily, but its taxa have shown a preference to forested areas and savannas at lower altitudes. Pitcairnioideae is highlighted by its level of endemism, but has only four species. Cryptanthus micrus, a new species found in this area is described and illustrated. Our cluster analysis indicated that the Rio Preto State Park has a Bromeliaceae flora more similar to that from Pico do Itambe and Grao Mogol State Parks. Taxa like Dyckia glandulosa, Orthophytum itambense and Vriesea medusa, which were previously considered to be endemic to Pico do Itambe, now have their area of occurrence extended to Rio Preto. These new occurrences highlight the importance to create a corridor joining these neighboring reserves to connect populations of narrowly ranged or rare species. In this work we present pictures of 19 species in their habitats within the park, and we hope that these illustrations will help in the identification and conservation of these taxa.
