Nacogdoches, Texas- Wetland Habitat Study Trip

   

Eleocharis parvula  

In the first week of November I got a chance to visit some precipitative wetlands in Nacogdoches, Texas with some friends. This area had received quiet a bit of rain in the previous week so the water level in the slough we first visited was a little high.  

    

This slough was very high in organics. In some portions it was almost impenetrable.  

    

As we laboured through this dense vegetation we finally reached the edge of the slough where our first interesting find was thalloid liverwort which we determined was most probably Pallavicinia iyellii . This liverwort was growing everywhere along the edge of the slough with some species of moss which we could not identify.

Next we spotted some Proserpinaca palustris. This beautiful stem plant is overlooked quiet a bit in our hobby. As can be seen in the picture below P palustris prefers highly acidic substrate.

We also spotted some  Saururus  crenuus in the same acid rich substrate. S crenuus seems highly adaptable to soil conditions as I have also seen this plant grow around Houston in soil with neutral pH.   

Saururus  crenuus   

The slough had a lot of Sphagnum sp moss growing around. Sphagnum sp moss has an ability to acidify its surrounding by taking up cations like calcium and magnesium. I collected a few strands of it to try in my blackwater Cryptocoryne set-up.

As we came out of the slough we spotted some very interesting mushrooms and fungi. I grabbed the opportunity to take a few quick shots.  

  

  

  

  

Our next stop was a precipitative wetland with some spillage form water bodies around .  The highly tanned water was about 6-10 inches deep in places which made the place look  like a black water habitat.

As we entered this wetland habitat I spotted some Eleocharis pravula growing among some dead leaves on the moist soil. This was the first time I had seen E pravula growing in its natural habitat. I was excited.  We also spotted some Eleocharis acicularis growing  here.

 This location also had a lot of Vallisneria americana . I had not expected to find V americana growing in such acidic water.

Our next interesting find was Ludwigia pilosa. There are a lot of pictures of this plant growing emersed but I was glad to see it growing submerged. This plant has a lot of potential as an aquarium plant. The crown of this plants looks stunning when viewed from the top.

 Looking around more closely we were able to spot some Juncus repens growing in the dark, tanned water. J repens though an easy plant to grow is not easily available through commercial aquatic plant nurseries.

We also spotted another stem plant here which I believe is a  Gratiola sp.

Walking around the swamp we were also able to find some very interesting critters.  First we found the Central/Eastern Newt (Notophthalmus viridescens louisianensis) hiding nicely among the underwater vegetation. The next one was a juvenile crayfish which I believe is a Faxonella sp.

We called it a day around 1: 00 pm and headed out for lunch. Thanks a lot to Darren who took the trouble to show us around.

Cryptocoryne pygmaea

Cryptocoryne pygmaea spathe

Cryptocoryne pygmaea is a relatively rare Cryptocoryne species from Philippines. It is an easy plant to grow in emersed culture. I have been growing it my freshwater crypt set-up since April, 2009. I used 80% ADA Aquasoil Amazonia and 20% pure laterite as the substrate to grow this crypt.

C pygmaea gets its name due to the very small spathe compared to the size of the plant. At times the kettle can be completely buried in the substrate with just the limb of spathe visible above. The kettle of  spathe in the above pictures was about half buried in the substrate. I had to slightly dig around base to expose the complete kettle.

Noticeable feature of the spathe was the rough inner surface of the limb. The spathe was about 3 cm in size. I wanted to slice open the kettle to take pictures of the male and female flowers but decided against it as the kettle appeared almost fused with the rosette.

If seen from the top the spathe is almost invisible with just the a small part of  limb sticking out. I spotted the spathe developing about 3 weeks back. The spathe finally opened up last Saturday.

Spathe two days before opening.

Staurogyne sp. ‘Low Grow’

Staurogyne sp. ‘Low Grow’ bloom.

I have been growing Staurogyne sp ‘ Low Grow’ for about 8 months in my emersed Cryptocoryne set-up. I have two more Staurogyne species (Staurogyne sp ‘Porto Velho’ & Staurogyne stolonifera ) growing along with this one under similar conditions and this one proves to be one of the slowest growing one for me. When I received a couple of stems initially they were grown submerged. It took a while for them to acclimatize to emersed culture. Finally Staurogyne sp ‘ Low Grow’ decided to flower yesterday. I think a recent increase in photo-period on my emersed set-up could have triggered the bloom.

 Staurogyne sp.’Low Grow’

Staurogyne sp ‘Low Grow’ grow very slowly in emersed culture even under good light. An interesting thing I observed with this species is its rate of growth does not change much even after moving it to a shaded location from a well light location. It grows about an inch every month in my experience under both high and low light conditions.

 

 

“Beauty in Red”

This photograph of  Red Cherry Shrimp aka Neocaridina heteropoda var ‘Red’ taken by me was selected as the Photo of the Week – Aquatic Category Week #58 over at  www.aquatic-photography.com  yesterday. This came as a pleasant suprise to me when I saw the thread. Thanks to Hristo Hristov and AP team for this accolade.

“Mountains of the Monsoon”

10G “Mountains of the Monsoon”

Rotala rotundifolia

Rotala sp. ‘Nanjenshan’

The inspiration for this scape came from the beautiful Western Ghats in India. The rain soaked slopes of these mountains covered in rain forest is a sight to behold. This scape has been my attempt to replicate a fraction of this beauty.  This scape was ranked 445th in the International Aquatic Plant Layout Contesst 2009.

This set up was started in the last week of September 2008 after I took down my previous set-up “Boraras Dream”. I used the same ADA Aquasoil for this set up without taking it out of the tank.

I know the rock do not follow the basic iwagumi/rock placement rule. But I added the 4th stone to the set up as the three rocks where just not anchoring the placement for me.

I could not find all the plants I wanted for this scape from the get go so had to start off with what I could find. This shot was taken just after planting and filling up the tank.

This is how it looked approximately one month from the start.

Approximately 1.5 months after setting up this tank the plant growth was just amazing.

The stem plants had taken over this scape within a span of 50 days. This is how it looked after the first trim.

These pics are taken roughly 70 days after the set up. I was playing around with the background trying to decide which looked better.

This was taken about 110 days after setting up this scape.

Brazos Bend State Park

In the last few weeks I have made a couple of trips out to Brazos Bend State Park (BBSP) near Houston after hearing about it from a friend. There are lot of aquatic plants around the park and some interesting wildlife. I could not do any collection here as this is a state park and collection is prohibited.

Echinodorus cordifolius were growing huge and were ominipresent around all the lakes.

E.cordifolius flower

Polygonum hydropiperoides growing through out the park were in full bloom.

As I looked around the bank of the lake for more plants and was trying to reach for some Limnobium laevigatum (Amazon Frogbit) , this guy waited patiently for me to do a mistake.

This beauty had ventured quiet far from the lake probably to lay eggs.

Pistia stratiotes and this Hydrocotyle sp was also easy to spot along the lake.

Sagittaria platyphylla was another plant common along the lake’s bank.

This yellow crowned night heron tolerated me quiet a bit as I kept on disturbing him as he hunted for his supper.

This guy was not so accomodating.

Cryptocoryne wendtii ‘Florida Sunset’ spathe

Cryptocoryne wendtii ‘Florida Sunset’ was introduced to the hobby by Florida Aquatic Nursery(FAN) in November of 2008 at the AGA convention.  It was not until March,2009 that FAN started shipping out this plant to its distributors. C.wendtii ‘Florida Sunset’ is a variant of C.wendtii ‘Mi oya’. In emersed culture the leaves are brown with shades of  pink and small amount of white.

C.wendtii ‘Florida Sunset’ is a easy plant to grow both emersed and submerged. It loses its variegated form underwater.This Cryptocoryne  is extremely easy to flower. My plant send out a spathe approximately one month after it was planted in my emersed set-up and has been putting out spathes continuously since then.

The twisted yellow limb of the spathe is clearly visible in the picture above. This is not typical of a C. wendtii limb which is generally reddish brown. The deep brown collar is fairly pronounced.

A cross-section of the kettle shows a short spadix.

Polygonum hydropiperoides

Polygonum hydropiperoides in my emersed Cryptocoryne set-up put out an inflorescence last weekend. P.hydropiperoides is native to both North and South America and is generally found growing along ponds and swamp margins.  Typically flowering from June through November,this plant had flowered for me in July of  2008 when I had just started my emersed set-up.

P.hydropiperoides is one of the less popular Polygonum sp. in the hobby. This is probably due to its less flashy colors as compared to the other Polygonum species.  P. hydropiperoides is a moderately difficult plant to grow submerged.

P.hydropiperoides has a straight upright growth pattern and tends to grow out of water if given a chance. Although this plant is not available from any of the aquatic plant nurseries it is easily obtained by collection throughout United States.

Houston Plant Fest 2009- Part 2

ADA 180P at ADG Gallery

The third day of Houston Plant Fest started early for some of the NASH members who volunteered to help Mike Senske prepare plants for his demonstration. Mike was gracious enough and offered to do a planted tank set up demonstration for the group which had gathered in Houston for the Plant Fest. The ADG Gallery was looking great as usual.

ADA Mini-M

The ADG Gallery also had  some great looking marine set ups.

As Mike and team prepared for the presentation some of the people who had arrived early spent  some time pouring over  Aqua Journals and gazing at the relaxing aquascapes in the ADG confrence room.

Ghazanfar, Thanh and Dave

Other than the beautiful aquariums, the ADG Gallery also has some interesting pieces of wood  on display.

Mike started his presentation with a brief introduction about his business and how he  and Jeff Senske have made Aquarium Design Group what it is today.

Mike was setting up a ADA 90P for this demonstration. He had decided to do a divided substrate set up with ADA Bright Sand in the front and AquaSoil Amazonia in the back.

John And Luis , helping Mike.

Mike’s demonstration was great as usual and was an amazing opportunity for people who had gathered to learn and discuss the intricacies involved in setting up a show quality aquascape.

The finished scape.

The Houston Plant Fest was graciously sponsored by Seachem Laboratories and Deep Sea Aquatics. Seachem had arranged for a lot of  free goodies for the people who attended the presentation at ADG.

Deep Sea Aquatics had donated an awesome  rimless tank setup to be raffled at the end of the presentation. Mary Beth, the winner of the raffle was definitely pleased with her prize.

Mary Beth excited about her prize.

After the presentation NASH had a impromptu plant auction. Kevin, did a good job as an auctioneer . There were some great plants to be had at dirt cheap prices.

From ADG Gallery the group headed to a BBQ party at Valerie’s Lake House on Lake Houston. Valerie is one of the founding members of NASH and was kind enough to host the BBQ party at her beautiful lake house.

Valerie’s Lake House

I arrived a little late for the BBQ party and missed out on some of the delicious food Kevin’s dad had cooked. But  just hanging around with friends, having some drinks together and checking out the beautiful sunset from the lake house made up for it.

Overall this was a great weekend which we all enjoyed as a group. On behalf of NASH, I would like to thank all the people who participated in the Plant Fest 2009. A big thanks goes out to Aquarium Design Group, Seachem, Fish Gallery , Houston Aquarium Warehouse, Deep Sea Aquatics, Valerie and all the volunteers from NASH who made this  fun filled weekend possible.
